I actually find the arena being a little bit harsh, or just completely hard. 

I have two accounts, and they are both ranked in the same division but the opponents I have to go through on my main account are completely on a different scale than my secondary account. In Bronze 4, I have to take on opponents with 40K+ Heath Pool's, that can also dish out, twenty thousand damage without an problem. 

Whilst on my secondary account being in the same bracket, only has matchs with enemy''s with much lower threshold's, and this make making progress, so much more difficult. Being a new player, I did not really realize the depth to this, but it has made getting back into my old ranking a real problem, though I have completed the grind, I did not know I was grinding my way into Gold I, it seemed completely normal. 

With my second account, being a much lower power than my main account by 300 thousand points, I only have 16k health, and deal 15k in damage, and I can not cut all these guy's down, can we possible have some kind of less restrictive enviroment in the game, while the top arena is based on point to point system, where it is actually fair to fight these body's
