I'm in favour of slight buff of fox but not much, not like that much, 30-50 overall armor would be enough. There are lots of possible exploitation with fox, if people don't wanna take that as exploitation, lets just call it advantages, and with those advantages considered, it shouldn't be considered under powered much.

I don't wanna hand count that all but it's always possible to escape buffs and come back for ez kills, sudden attack, ctf exploitation with flag just to name few.
