No need New characters, need to correct bugs

Are you saying that the rng should be changed so that battles ran the same every time? So remove rng completely? Some games are like that. Not this one. It's not a bug. 

If auto mode was better, as in it played optimal moves every time like a player should, it would mean enemy teams played like that too, making many battles near impossible for players to win.

If you are setting auto and think it's making the bad choice of just attacking the leader, that's actually your choice. When on auto you still have control of the target, unless you tap on the current target to remove it. Once you have removed your preferred target the game will start selecting its target just like the enemy team does. Usually it chooses the closest to death opponent,  unless there is an enemy on the general priority list, like GMY, or the particular character has a priority list of its own. But again there is rng involved, sometimes it chooses someone else.

Conquest enemies outspeeding you is not a bug. There is a starting enemy stat bonus to every sector, that bonus increases along the map as well, and some teams have an over prepared modifier too. Add to that the faux-mod bonuses each toon has (I think), and yes, they are very fast. But they don't get data disks. Plenty of people can figure out how to beat those fast enemies.

Are there any actual bugs you would like them to work on?
