1.) current raven design
2.) battlecruiser/thor/terran T3 in general
3.) fungal lol'th
4.) tvp lategame aoe frontload damage vs low hp terran bio leading to drastic snowballing battle advantages
5.) the 120 ling remax after terran trades with infestor broodlord (if T is lucky enough to make that trade).
in tvz, if terran can't finish off the zerg with a 2-2 push before greater spire, should terran grab a 4th base with extra starports and then begin setting up massive defenses such as positional planetaries, more bases, and then tech to mass sky terran?
