And yes, I don't have keybinds to consumeables, throw ball or my relic. I just click them...and no this doesn't make me bad in PvP.
To the left are some WASD+Shift binds, including those "useless" skills. On the right action bar are the mandatory buffs, which are bound to F1-F4. My Lightsaberform doesn't have to change so it is not bound either, just having it on the bar to confirm its active, sometimes buggy.
I don't even use keybinds in conjunctino with ALT or STRG (strg is default bound for companion skills anyway).
And say Crushing Blow is the same as Vicious Slash, just because its a "weaker" Rage dump is just not true. CB is a talent, not everybody is going to take it and if CB is on cooldown you have to use Vicious Slash if everything else is on CD, which I encounter pretty often.
Edit:
I also use only one extra mouse button, the other is bound to push to talk for voice programs.
