Ok, my thought process on my arena team us this, and it started before modding with the huge hitting teams with leia, rey, etc.....why not lock as many ppl down at a time as possible... i was considering
Dooku(l),rg,daka,han,leia
Leia would be a hard first target given stealth, daka has decent health, rg more do, han wpuld mess with tm, and dooku has ca... no good options in order..plus taunts would complicate matters Then if you can lock down the offense since you have 3 stuns it should be a nice team....the stuns will help even more now as that is currently how im hsndling mega hitting modded rey. I use rg and no longer an issue.
With mods i think ill be even tougher, especially if the speed mods offer a bit of health as seconaries...
Of course i hay be crazy in my idea too lol
