There's no flow to the really fucking sunny one. Also it's really fucking sunny. The rocks on it are difficult and frustrating to jump up to the middle ridge thing. You can position yourself near an edge and the enemies can't shoot you, but if they get a good grenade, it tosses you off the map. Great spot for trolling with the ball.
The green one(I think that one was Shitter) has even less flow. Bases are campy. CA power weapons galore. Camo + Sniper ruins it. Frame lag up the wazoo.
Harvest is okay. Right now it suffers from bad gametypes. Ball on Harvest and KotH on Harvest aren't fun.
I was just complaining to Sai Kun about how bro spawning is spawning enemies on top of me in my own base because I'm fighting another enemy in CQC. Awful stuff.
The worst part is how the weight of bro spawning has really screwed up any form of coordinated attack. I remember an old strategy a few of my friends and I did on Valhalla where two people went Warthog through the water, I went through the caves, and a couple people positioned themselves top middle. One of them would intentionally die in the middle every 3 minutes, so he would respawn near the base and grab the Sniper and bring it back to the middle. It doesn't work anymore because it spawns the guy right by me in the caves. I'm attempting the same sneak strategies and being thwarted not by the enemy or my own stupidity, but because of the game. There is no such thing as sneaking any more. Waypoints killed it. Bro spawning killed it. Camo on spawn killed it.
