I am getting tired of beating players online with a well managed, upgraded, and microed illuminator/guardian/mothership fleet only to hear the tired excuse "illum are SOOO imba."
Let's forget for a second that illums:
-Require three research labs
-Are by far the most expensive long range frig to research ($800/100m/175c vs 400/0/25 for assailant and 600/50/100 for lrm researches)
-Are the second most expensive long range frig to purchase ($380/60m/55c vs 400/65/45 for assailant and 275/45/25 for lrm)
-Have the longest build time (in fast speeds the build times for illum/assailant/lrm are 24sec/23sec/21sec respectively)
-Have the shortest range of all the long range frigs (5520 vs 9800 for the assailant and 7820 for the lrm).
Let's also forget that advent have the
WORST econ.
Let's FORGET all of that for a second.
Let's instead consider that in addition to building a healthy number of illums fast (20-30), I also work hard to get at least the first 3-4 levels of shield and hull upgrades, the first 1-2 levels of weapons upgrades, the ability upgrade (deceptive illusion), AS WELL AS supporting the illum fleet with guardians and the progenitor (w/ malice + shield regen abilities).
Let's also emphasize that such a fleet, as powerful as it has the potential to be, will get utterly WIPED if not microed well. By default illums like to assume a stand-offish position which allows their front beams to fire only. Effective microing of illums is ESSENTIAL to ensure that
a) they are positioned for maximum arc damage (ie all three beams are firing),

you capitalize on the illum's ability to fire while turning, ie constantly reposition the illums to force the enemy units to turn, while the illums keep blasting away.
In addition to microing the illums, it is also imperative that the mothership and guardians are microed well so their abilities are used with maximum effect.
If, despite the prohibitive prices involved, with worse econ, I am able t build an equal sized or larger fleet of illums then a vasari/tec player can build their own long range frigs/HC, and if I've been able to upgrade my illums several levels, and if I've also been able to build support ships, and if, finally, I am then able to wield such a mighty fleet well, with effective micro, I THINK I EARNED TEH WIN.
The only thing that is "imba," perhaps, is my own skill vs that of my opponent
