You're crying about 1 new ability? Seriously?
Some classes (like Gunslinger) do seem to suffer some level of ability bloat. When you have 3 hot-bars of abilities that you actively use and a fourth hot-bar of abilities that go unused. That IS somewhat cumbersome.
On the flip side there is Commando which has like 5 abilities in total that get used at 50.
Trim a little bloat here, make some things passive and add some better abilities there and i think it would be a benefit long term.
