I like the new runes but the Precision tree needs a rework IMO
The Precision tree is problematic for a bunch of reasons. Firstly it's way too class specific. The only class that will ever feel great using the keystones in this tree in its current state is marksmen. I just don't think that's the right direction for the new runes. I'm not saying every keystone should be good on every champion but no path should be so tailored to a single class.
Secondly none of the keystones in this tree cause a player that would use them to play any differently. Oh, you took Press The Attack? Well instead of autoing as much as you can, it's better now if you auto as much as you can. Same story with Fleet Footwork and Lethal Tempo. I'm not against a keystone that benefits auto attack focused champions but at least design it in a way that their auto attack or engagement patterns are altered in some significant manner.
Compare any Precision tree keystone with the experience of taking Unsealed Spellbook, Predator, Dark Harvest or Kleptomancy. Those are all runes which give a player something interesting to manage and play around. The way you play the champion is changed because you have one of those keystones.
I'd just like to see the keystones in Precision to not be as easily quantifiable as they currently are. And also that they'd require some degree of management on my part to be able to make the most of them and so I can actually tell I'm taking a keystone.
because these days you either one shots squishies or die to tanks.
