I am surprised how noone said Redeye as rediculously strong as he is with the PDP currently.
But maybe it is due you being a newer player and he takes a bit of knowledge.
For Thunder, he only seems a viable choice with a Timik loadout. His default MG makes him too slow with only low damage to dish out. His concussion nade (with built in EMP!) is pretty underrated and works wonders especially in Execution mode, but also on any game where healing stations are a problem, that cant be easily spammed with explosives. The EMP disable does the trick and you bring a lot of HP to the fight following.
