^ Yeah they might change things of course, but the masteries as they are, are enough to completely negate the nerf + a bit more (it goes down to 256 or something).

And even though you have to invest in it, it now is a lot easier to do so since it only requires 8 points to get that advantage... In previous season you had to spend 21 points to reach a similar advantage, so if anything they made it easier for most roles to get that advantage.

For example any AP mid or AD carry can now run 21/0/9 and get a very good flash on top, while previous season that was pretty much impossible as 9/0/21 wasn't a viable tree for AP or AD carries. Add in that supports will go into the utility tree as well, and some junglers have that option too (think tanky junglers like Amumu, Maokai and Nautilus) and that leaves pretty much only solo tops and the more offensive junglers that really can't afford 8-9 points in the utility tree.

Anyway that's just what I think, but we'll see what Riot will do these days/weeks on the PBE/live servers and what people will do.
