A lot do think so, but why should you implement it? Don't tell me you are not able to set your masteries within a minute...
While it's been said many times, I'll say it again for everyone. No one said anything about not being able to change masteries in a minute (although, to be honest, with the lag between clicks sometimes even THAT can be difficult). Problems arise when there is very little time to change masteries and lock them in safely. This should not be a problem, period.
But it is, and has been, for some time.
Riot, why? Shouldn't it be relatively easy to implement this? I understand some people don't think it's a necessity, and that's fine (maybe they don't experience the lag in adobe air). It would be, however, a great convenience to have them all setup and not have to worry about server lag or not having enough time.
I'd LOVE to at least hear what Riot has to say about this. Please?!
