No one is going to be in this situation like me owning 123 champions, but I'm going to throw this out-there anyway. So the aram ReRoll system looks like this:
*+30 points per game plus 1x number of champions owned; 250 points = one Reroll up to a maximum of 2 Rerolls (500 points max).
Here's the deal: If a person owns 95 champions, they can get a reroll every other game (30+95 times 2 games = 250 points)
SO...you can own the best 95 ARAM champions AND get a reroll every other game, I know it's a very random format but, the very, VERY UNFAIR point is that a player can CUT OUT the bottom 36 champions (131 total atm) from their champion pool. (YES there are websites that have aram win data on all champions {such as metasrc.})
So what I'm suggesting is that players with over 95 champions, should get a Roll-Over amount of Reroll progress, yes kind of like cellphone companies...so that maybe every few games they would get a special third reroll to have in stock.
Im not saying that you should have 3 rerolls in champ-select I'm saying 2 max rerolls. AND THEN the 3rd reroll would just max out your 500 possible points if it fell below 250.
Here's an example: if I have 500 points, I can have 250 possible floating points to refill my 500 if it drops to 250/500 or below.
