quick look at fire:
kevkev bans:
SoG, bone wall, and dimentional shield all means that kev doesn't want to face fire stalls
EQ is probably just because napalm could ban immo, and thus towers/pends will be the only quanta producers, which will be very weak to EQ
immo and nova are most likely to prevent rushes
napalm bans:
bone wall, SoG, dimentional shield, and lances are again to prevent stalls (most likely)
EQ again is to prevent total lockdown
steal was a rather interesting ban, as deflag would probably be a better ban, perhaps he was planning on a permanent heavy strategy, and doesn't want the permanents to be stolen (most likely farenheit)
