Hopefully the ability on them will actually become useful...hell, they could be made to be a counter against Titans if things were done properly...

Not saying that's the best use for them, but it could be a use...

LRMs get insta-popped by Titans...corvettes are practically non-existent...

Their cheap cost, fast build time,  anti-all weaponry but fragile health tells me they are intended for use as a quick spam defend your grav well kind of militia for when you need some numbers to counter an invading fleet quickly. I think flak frigates will still be a better choice vs. fighters and LRMs if you have the time to build their numbers up in advance.

I think Ekko has a point.

But you're right, Seleuceia. I'm used to EVE Online where larger guns have difficulty hitting smaller targets (in addition to calculating trans-angular velocity among other factors.) 

I was expecting this to be the case.

I also hoped Corvettes would have more of a tackling role as seen in EVE as opposed to cheap fodder, I launched 50 or so Corvettes at a capital ship and did not see its phase jump rate slow by more than 20%.

I find them quite effective early game (on smaller maps) to send them out where you think your enemy homeworld is and cripple their early game constructors. Seems ridiculously effective!

I also don't really know what corvettes are good for.

In the Homeworld games, ships in the corvette-type class of class were generally anti-fighter ships; they had guns that could track fast enough to hit fighters, and the corvettes themselves _moved_ fast enough to not be hit by the big anti-capital ship beam weapons.

That said, ships in Sins of a Solar Empire don't really move during combat.  With the exception of strike craft, they more or less line up and just shoot at each other, pre-20th century stye.  I'm not arguing that ships should move and force players to micro-manage - I'm all for the grand-strategy scale of combat the game currently has.

I'm just trying to make the point that if ships moved during combat, controlled by the computer, that could be a distinguishing factor, and another strategic element to take into consideration when organizing your fleets.

My suggestion would be to buff their chance on hit abilities, so for example a higher chance to add a higher-stacking debuff (20/40/60/80% reduction in phase jump charge rate, 20/30/40/50% reduction in passive hull repair rate, though obviously these are arbitrary numbers and could quite possibly make them too good).

As it is currently, it seems to be a very low chance and only stacks up to 30%, to the point where throwing 80 corvettes against a single ship can see a mere 10% debuff (seen times when it doesn't even get applied once) for their combined attacks, and even when it's increased to 30%, it is so insignificant  (moreso for the phase jump increase then hull repair rate decrease) that it makes it hard to justify their cost, especially considering how quickly they get killed off by any significant opposition.

I feel this would also make them feel as a more unique addition, where you'd use them in hit and run attacks to isolate or slow titans, or cripple certain ships/structures before committing your main forces, rather then use them as glorified light frigates that don't stay still and are much more likely to explode when sneezed at.

Give them a survivability ability that you can research, maybe something like "Evasive Maneuvers" where they have a 10% chance to shrug off each attack volley. That'll make them more like a persistent swarm of killer bees, rather than a swarm of gnats.

I don't think Corvettes should be anti-Titan. Just let the anti-module ships fire at Titans, with a chance for the titan to evade their shots (i.e. the shots would be far less effective against a Titan than an immobile Starbase, but still better than shooting it with conventional weapons). OTOH, to make Corvettes more useful, I'd be in favor of increasing the maximum amount that they can slow down jumps. This would allow a well-prepared player to field Corvettes against an enemy Titan to prevent it from escaping through the phase lanes when it's low on hull. You'd still need to be able to destroy it, probably using a combination of capships, heavy cruisers, starbases and your own Titan; but at least this way you'd be able to ensure that the thing actually dies, instead of escaping with 10% hull.

This is important because otherwise Titans don't exhibit the risk and the commitment that Sins is well-known for: it takes so long to destroy one that any average human (or a smart AI) would be able to survive all but the most catastrophic defeats with their Titan intact (especially if the Titan is defending a system owned by its own empire; if attacking an enemy system, Phase Disruptors may be a slight problem if you can't destroy them on your way out).

By allowing Corvettes to effectively block the escape route for several seconds longer, it makes the escape that much more difficult, giving the other empire a large window to destroy the Titan.

Even as someone who plans to use the Titan as a key component of my assault fleets, I would like this mechanic very much. Before Titans, the "commitment" of capital ships to a battle was a fairly serious move: you needed to scout enemy grav wells until you were really sure that you could take on the defenders, and make sure you either cut off reinforcements or ensure that the nearest significant reinforcements are far away. If you failed to do these things, you could easily warp your cap ships into a grav well with multiple things preventing them from leaving, and their survivability is such that they couldn't escape in time before being destroyed. Not really the case with a Titan; even if they have multiple phase disruptors, you can usually kill them and still get out.
