Let’s see what abilities I have that are useful in a raid encounter on my Druid (since I’m on him right now).
Main Action Bar (to =, in no particular order): Starsurge, Insect Swarm, Moonfire, Starfire, Wrath, Wild Mushrooms, Detonate Wild Mushrooms, Root, Hurricane, Regrowth, Cyclone, Lifebloom, and my trinkets/Lifeblood. Alt-Bar One (Ctrl-c, z, s-D, a-1 through a-4, x, s-v, v, alt-):
Starfall, Boomkin Form, Dispel, Cat-Dash, Solar Beam, Nature’s Grasp, Typhoon, Innervate, Treants, Rebirth
Alt-Bar Two (Mouswheel +ctrl/alt, alt-Q, alt-W, more mouse buttons):
Thorns, Barkskin, Warstomp, Hibernate, Soothe, Tranquility, Faerie Fire
That’s 31 abilities which are useful in combat. It doesn’t count out-of-combat abilities, of which I have seven which I need handy at any given point (Flight Form, ground mount, aquatic form, Revive, Mana Cakes, Pineapple Punch for when there are no Mages, my Alch non-consumed potion), and it doesn’t include healthstones, mana potions, and healing potions, which I haven’t bound yet because I’ve yet to have them/use them.
That’s a huge number of abilities. Huge.
