Talents

Why don't we have Talent Trees yet?

I've been wondering about this since Odyssey actually. At least one person at riot has the wherewithal to produce compelling gameplay components like that from the augments we say in that game mode. Sure they wouldn't necessarily all work for SR, but I'm sure they could be paired down, added to and altered to make something functional and enjoyable.

DoTA has one which is pretty decent: Simple, doable in theory if not exciting or usually hugely impactful on gameplay, but they also have Aghanim's Scepter which changes Hero abilities either through a buff to an integral part of their kit, altering it noticeably or significantly, or adding new abilities entirely.

What I'd really like to see is something closer to the HoTS model or like the Augments: Ways to upgrade and 'build around' skills that are hugely impactful to gameplay and allow champions to be played differently depending on the individual. Hell, Ziggs could be a healer in Odyssey, why not on SR?
