Hi,
Personally, I'm not a big fan of PVP/Arena battles, but the gameplay for Arena in VF is really interesting and it sparks my interest in Arena. But what turns me off is that.. I'm kinda being 'forced' to fight OP players in rank, bronze 1. That's like right at the bottom of the ranking. ""OTL
I do know that I can re-pick but using the arena orb is pretty expensive, as it takes an hour to replenish. I'd suggest a free re-pick or at least set the limitation of free re-picking 3x before spending the Arena Orb.
Just manage to get a number of 4* units and it gave me an opponent squad of 5*. It was a total one-sided elimination. OAO;;;
