Giving moderate buffs to Grandmaster traits is not enough. You need to give viable options for the traits you have to take BEFORE you get to the Grandmaster level. Having to pick weak traits just to get a mediocre Grandmaster one will send people back to water/arcane.
Also is it too much to ask for Tornado to not completely suck, and for the Elite elemental glyph to start its cooldown when the elemental is summoned, not when it dies?
