Yea saw that earlier today because I was making my own list of what runes had been revealed and found it looking around the LoL wiki. Credit goes to DeathBurst for making it.
Based on what I've read in the comment section, rioters confirmed that this list is pretty accurate so far but still subject to change (tm).
My impressions so far
Sorcery Tree
The Keystones are decent. Not a lot of runes revealed so far but the one's that have been look really strong. Ultimore, Overcharger and Gathering Storm are all interesting. Probably intended for most mages and enchanters.
Domination
Map control and roam tree, I see a lot of champions dipping into this tree as a secondary path. Definitely oriented toward assassins and perhaps junglers.
Precision
We know very little but it looks like standard adc-things dialed up a notch. Wonder if they'll get anything unique or interesting.
Resolve
Most boring tree imo but it does have some wiggle room to improve. Essence Thief looks interesting but probably only good for an extra 100-200 health if a game is short.
Inspiration
The most wtf tree, it has lots of interesting ideas but not a lot of symmetry to it that calls out to a specific class of champions. Might just be a secondary tree that champions opt into or for champions that want to build oddball and/or frustrating builds (ie Teemo, Heimerdinger). Might also be situationally good for junglers with Summoner Specialist and Channel-Blink? IDK
