Starlight is the only way to end massive FFA games. Until far in the future, when sea is fixed, land is perfect, and the devs can work on a better endgame FFA, Starlight should stay OP.
Disco is good for cost- a significant amout of shields can block most of it in crazy FFA games.
Funnyweb is not that OP (1 or 2 can be shutdown by vandal spam), but it does need a cost boost as to make the Dante a viable option instead of just spamming funnywebs.
EDIT: I say this because funnywebs hard-counter maurauding Dantes and don't stack much better then Dantes, so Dants are thusnot half as common as before.
Sea needs to be talked about.
EDIT: The couple sea maps I remember playing a few weeks ago mostly ended up being all about sniper-subs, carriers, and scallop spam. I think either more units in the ship/amphs/hover factory need to be retooled to fight in a 90% sea setting or more units need to be introduced.
EDIT: Snugglebass made a point regarding negativity. Thanks to the devs for continuing to develop an awesome game!
