Globalizing masteries
I'm looking at the tier 2 masteries, they should be a common throughout the whole game, without the need of a point.
Feast is so good. And I like the idea of early sustain to be able to stay "matched up" vs big sustain champs in the solo lanes, or in any lane where they have heals and you dont.
Secret stash same as above.
Explorer This would make it better for players that love to roam, then you won't lose too much on lane exp when you leave.
Another one is perseverance. Plus players usually pick summoner cooldown over this anyways. . why not globalize it for the first 10 mins of the match.
