ARAM suggestions

1. If someone dodges you should have the option of keeping the last champion you had from the previous champ select
2. Unlock all champions in the game mode and rework the reroll system to a more weighted-roll system (example below)

Example: (obviously open to change) You have a possible of 5 total rerolls that are built up over time through games in a manner similar to the current reroll system.

• Upon using the third reroll in a single champion select you are given the choice between 3 random champions.
• Upon using the fourth reroll in a single champion select you are given the choice between 5 random champions.
• Upon using all 5 rerolls in a single champion select you are able to hand-pick the champion you wish to play.
