Camus skills

If you're going vantage (which I prefer on Camus over QR anyways), I would go with fury instead of TA. But anyways, vantage 3 will give you a SLIGHT increase in score over QR 2 (probably 2-8 points total, hardly noticeable)

I run Camus with Fury 3 and Vantage 3 and I think its his best build. He has enough speed and bulky to benefit from Fury and Vantage is good with any distant counter melee unit. He gets to 57 attack and 42 speed with hone cavalry and fury, enough to one shot squisky red and blue mages and to outspeed
and ko most melee units

camus runs better with vantage. Quick Ripost is for units with bad spd.

Fury 3 is used in conjunction with Vantage since the recoil damage brings you low enough for it to activate. If you want an alternative to run Quick Riposte safely without knocking yourself out of the threshold using Distant Def 3 can be an interesting choice.

Fury(and helps you to come faster in Vantage) is one of the best skill in arena.
QR and Vantage plays on same lvl depends on situation. Sometimes you need 2 hits thx to QR to finish off enemy or to save camus from deadly finisher thx to Vantage depends on situation and enemys.
Let be real with 36(with fury) spd he will rare double with QR you still have in a defensiv fight 2 hits.
Depends how you play.

But overall think you will fall in arena if you have not alteast other merged heroes wih +5.
