I'm gonna co-main lantern and aquaman from now on. Together they handle the whole cast pretty well while remaining similar in principle/play style. Batman gets rocked in this MU unless the batman player has a ton of experience in it, and then it's just a rough fight instead of a blow out.
Have yet to fight a good cyborg.
It's funny because aquaman works better for me with SF controls on. Since he's so reliant on d2, getting trident spike from going down > down+back and pressing 2 was happening almost 50% of the time. So, rather than break capcom habits like that (which are essentially good habits in almost every other circumstance) I use alternate controls.
The only problem is, you can't switch control schemes while online, so I have to go all the way back to the main character to change characters. I'll sometimes still forget and pick GL with alternate controls and just let myself get bodied since I deserve it.
