hmmm, i thought their econ bonuses over other races were LESSENED, but not removed... i could be wrong. at the very least, it is a fact that their power upgrade is cheaper at 150/50. also, i usually have 4-6 gens by the time i get into T2... in my games with IG (granted its only the 1300-1400 level right now) so far power has never been an issue.
also, i wouldnt exactly include buildings durability in with econ, that is a whole seperate issue. the fact is, their LP2s cost less power then every other race, which means it is easier to get their econ rolling WHILE teching at a solid rate.
also, 250/150 for T2 is the same as every other race more or less. chaos T2 costs 300/100 and marines is also 250/150.
and finally, it is also the least costly for IG to tech to T3, as they ONLY need a mech shop.... i have been able to make it to T3 in at least half my autos so far.
not really... you can either sit their with half the econ or spend the power to even it out. the whole point is that you dont have to spend as many extra resources as them to keep the same econ (55 power extra, compared to any other race using 75) despite them having more points... and this is really only an issue on specific maps. also in T2 you can make a serious push out with sents (decapping crit points if you have to and raiding their econ/decapping outer points) and/or a basilisk.It's kind of pointless LP2ing all your points when you have say, only 4 points because your opponent can match your econ simply by capping critical locations and relics
