I'm not happy with spamming Percys and shields all day. if i want to break a bunker i use 7 percys and 5 shields instead of 10 T3 artys. Or 2800 DPS with 65100k hp and 17500k HP instead of 700 DPS and being so weak it needs to be babysitted all the time.
But what about the t2 vs t3 balance? Well Loyalists, harbis and Titans utterly destroy them anyway, so good t3 arty wont affect this too much.
@Anaryl: thats basicly one of the big points i think. T3 Land is effective vs T4, but only if your opponent decided to play the t3 land game with you and you have a decent army before the first GC/Monkey/yotha shows up.
Exp without support should not outright pwn everything imo. The only thing where i see this is true is Fatboy (ofcourse) which makes him the worst exp as the other 3 main assault exp (yotha(GC(ML) can be just spammed all day and do massive damage. Espeically GC with a few shields and hover flak is a more comon sight then a Harb army in lategame.
And i'm pretty sure we all know this or do this ourselves.
After all a rushed Exp mostly only works because your enemy lets you the time to do it instead of attacking you.
Its pretty hard to attack into a defended base especially when your not in position to attack immediately. Slow speed is the only thing that hampers Heavy assaults.
So if your not knocking on his door and he has a 30% exp. when you scout its commonly a better decision to retreat and bunker up/build air then to attack into an exp that will be finished by the time you get there. And don't forget OC from the commander that should be in base at this point as well. Killing eco is pretty cost ineffective with t3 because you leave him a good portion of your own mass to rebuild. And if he defends well and you suddenly have no army vs a exp..... its a g to the g no re.
