Is the balance team full of marksmen and assassin mains?

Feels like new mastery trees were based entirely around the needs of marksmen and assassins. Mages and bruisers in particular and to a lesser extent supports and tanks seem to have been pretty shafted by the changes. Now that aerie has been nerfed I now have the choice between comet and... comet. Wonderful. Not only did we have the ability to customize our runes taken away from us with the new mastery ahem rune system so if I'm versus a Zed I can have a fantastic 8 health at level one (woo!) but we also now only have a choice of one keystone. Tell me again who at the Riot balance team thought this was a good idea? facepalm
