Summoner Spell Balance/Fixing Flash Suggestion

This is inspired by rival suggestions that should be universal and that it should be removed from the game. It's without a doubt the strongest summoner spell. Most gameplay is focused around the use and availability of the spell.

Point System for Summoner Spells 3 Points to spend costs 2 All others cost 1 All spells can be upgraded for 1 additional point

This would incentivize opting out of because you get an upgraded version of one of the other spells. It would also allow for an upgraded version of at the cost of a second spell. It reintroduces summoner spell upgrades which I enjoyed from the old mastery trees.

Most importantly, it adds a lot more variety of gameplay.
