What I don't understand is:
Is the S3 Mastery Tree overall made to help champions early game or to multiply their stats late game?
Is the S3 Utility Mastery Tree for early game or late game?
If you go 21-9-0, you do tons of damage while having a bit of survivability, and do even more damage late game (?)
If you go 0-9-21, I'm assuming that you get some sustain, regen, cdr, movespeed, exp and gold bonus.
But you would lose a lot of damage, so it's not beneficial early game.
Late game the regeneration is terrible and exp/gold bonus is useless because you're already level 18 and fully built. The movespeed, cdr, lifesteal/spellvamp are left. Movespeed and cdr are fine, but if you're getting lifesteal/spellvamp anyway, then more damage means more health gained back.
Which means, Utility is worthless early and late game.
Does it help mid-game? No, it just helps you get there faster and safer, but since your early game is worse, good enemies would take advantage of that.
Wait, so you sit back and farm? Is Riot encouraging boring passive playing? Farm until 20 minutes then team fight?
I'm confused about the purpose of the Utility Tree, on anything other than support. Junglers also take more damage now so I'm sure 21 points in Defense, or at least Offense, is necessary.
