LE + QoT +UB is pretty strong in my mind for pro teams that I don't see often enough. You have a 6 second chain stun and an armor penalty multiplier that exceeds the typical armor you can stack in addition to a semi-decent support unit that can shield to allow tower dives or saves.

For normal teams Rook + UB + Oak is crazy strong. You have skill/item blockers on all demigods and a snare / damage multiplier / chain stun / power hit that is usually fatal with little effort, in addition to team shield saves and flag cap shenanigans and all around FU push power.

Rook&ub (2 best DG 3v3) + sed\oak\ereb. Sedna silence (!!!), heal & conterheal. Oak shild & penitence (increasing all damage taken). Ereb charm.

maybe 3 full minion general? (ring of divine magic, gladiator glovers, sigil, 3 idols 1lvl, moral - fast mid destroy) but its not hf ...

Agreed

Agreed 100%. This combo does the most damage fore sure. I mean armour reduction is crazy and with ub coming in other team has no chance. Erebus stun prevents any escape possibility, usually person is dead by the time stun wud end. Problem with rook is that he gets the hammer going too late. And his towers dont do anything against qot. Same thing with oak. He gets going too late. Qot ub and ereb they are all the most powerful units early, mid game other team has no chance to do anything about them i feel. Also i think erebs stun just so much better then oaks stun for killing enemy.  In theory  with this combo the game shud finish before oak or rook gets powerful.

The most important is the coordination and a plan. If you have that in a 3-player team you probably kill everyone in an instant. Lots of good combos have been named. How about a DA swap on Reg mines and then having an erb stun or stun after the slow is over from the mines. Think its easier to do than the chain stun of erb/ub/rook as there you have to time 3 things in a row where with DA/Reg/Erb the timing is not sooo important. But if you assume perfect timing of everyone the erb/ub/rook is probably more effective.

Especially early game a QoT in Rook towers with a finisher like Reg, DA or UB is also deadly.

tis only theory crafting, folks

I do think the strongest combo is ub/rook/erb, though.  Swapping oak for erb doesn't hurt all that much, though.  I'd just prefer the additional lengthy stun and the ability to batswarm into any combat after lv10 instead of a slowing pent/surge. 

mayhaps - we prob just disagree on this one for various reasons. Definitely pros and cons for both.

UB DA EREBUS duhhh

I'd be willing to give it a go on the qot/le/ub side, but I think the outcome will be what you'd think. 

With re: to oak/ub/rook - there is still a point to including the shield in the discussion, though - granted, its used for saves, but it can also be used to buy your teammate some extra time for a kill, etc... so while it doesn't contribute directly to the dmg, it does buy whatever dg that needs it an extra 3-4 seconds for abilities, etc, which contributes to the overall dmg. 

I love the da/erb combos.  I think I've played like 2-3 games there were solid, very coordinated erb/da's on the same team, though, working for ganks.  I really wanted to work that combo in one of our 2v2 tourneys but that didn't work out.  Love the spam dmg at 15 on da.

I think in terms of mid-game killing potential, Rook, Erebus, UB by far. Rook can drop towers (esp with Amulet) for ganks and winning 3v3 conflicts and it's very difficult to escape that team. Late game, Oak is better than Erebus.

How can you not have ub in a gank setup...

da reg tb is hands down the worst team.
