I think some of this thing are wasted repicking another opponents so I just got an idea, how about repicking(and finding match) opponents only uses gold(amount of gold used-up depends on your level) and arena orbs will be used-up after the battle. I know this might not be a good idea and some of you say "use strategy and tactics dammit" but think about the people in lower leagues, in 1300 you can see some people(probably p2w) with five 5* heroes while you still have one or two 5* and two or three 4*.
Question: Who would battle those people with full 5* heroes if this kind of thing happens?
Answer: Probably another p2w or people who like intense battles (boring stuff is no fun duh).
I know this is kind of stupid(or really stupid? lol) but please consider it. Also do something on PVP, it's full of meatshields, THIS IS PVP NOT STARING CONTEST!!! Well, that's all.
