Ugh, see that's exactly the problem.
My hotbars are so full of threat tools, that I need to be accessing on .2 seconds notice, that I have to macro things together like cooldowns, so that there's enough room, even if it's impractical to macro them together. Cooldowns, that I also need on a .2 second notice.
I'll break down my bars--
L2 + Dpad
Cover
Shield Swipe
Convalescence + Cure macro'd together
Rage of Halone
L2 + ABXY
Sprint
Sentinel
Hallowed Ground
Awareness + Bulwark macro'd together
R2 + Dpad
Rampart
Shield Bash
Riot Blade
Provoke
R2 + ABXY
Flash + Circle of Scorn macro'd together
Shield Lob
Fight or Flight + Fast Blade macro'd together
Savage Blade
I could move Sprint, but don't want to for the comfort, and for the places that it's needed, it's really needed.
I could move Circle of Scorn, no denying that.
I could move Cure, however keeping Convalescence handy makes sense.
I have nowhere to put Guardian's Will. Unlike other cooldowns, it's a waste to use it beyond its specific purpose.
I have nowhere to put Spirits Within. I would macro Bloodbath from Marauder to Spirits Within.
I can stack foresight into something else, but I'd prefer to keep it separate.
Paladin tanking has two types of abilities in this game. Abilities you're using every few seconds or abilities you need in a second's notice. There's not much for "forget it" buttons.
