The thing Schod is forgetting to mention is that while he's 90% right, the 10% is the fact that the Vasari are a little under-powered in the early game. Fix that, and maybe
weaken them in the late game, and things work out better.
I've reitterated a zillion times that I agree the Vasari are exceptionally weak early on and should have their techs brought down a notch, numerous times.
well just wait a second. protoss shields are far from a minor characteristic. every decent player would have many shield batteries and withdraw injured forces immediately to them. also great on the offense. siege tank ring a bell?
again its minor, yeah so if you're losing on defense late game you would pull back to a healing position, uh, duh. the Terran have medics, would not you use them to heal to? differences: one is better the other is mobile
the TEC vs. the Vasari is far more in depth, phase lane movement, interdiction, focus on survivability rather than active defense etc. etc. I'm beginning to think Starcraft is too easy a comparison.
so in short, yes Protoss shields are a minor characteristic, at least in comparison to the way in which Vasari use their shields.
anyways, if you want I can elaborate on all those details. my point is not that is the only way to differentiate in sins, but that its an additionaly way. more differentation is better than less, isn't it? and even if some of them are shallow, so what? I said earlier there is a gameplay differentiation which already exists with vasari, if only at higher lvls (but blair stated they might move some of it down, which is good, you too admitted that AND differentiation should be more present at lower lvls), and there is a felt, a perceived differentiation. implementing some of those things to make them feel different even if the gameplay effect isnt all that major is still more than worthy of consideration.
the problem I have with your argument is not that you're promoting differentiation, rather that you are promoting the degredation of current differences in favor of percieved, 2-D differences of stronger/weaker more expensive/less expensive.
