Yeah I'm pissed my warrior can't use hallowed ground

Forget Hallowed Grownd, warrior can't use sentinel or rampart. It's pretty silly, Paladin can have Warror's 20% boost to armor (Foresight) but Warrior can't have paladins -20% damage taken which is always better than a 20% boost to armor.

And no, OP, please no. 1.0 had exactly what you're asking for and it created two things- 1) Tankable mages and 2) "Fire" burns (pun intended!) where everybody, tank, dps, healer, equipped Fire cast it on a group of mobs. It was the fastest exp you could get without outside help.

I want more job customization, but not to that extent.

That said, there's no reason Warrior can't use half gladiator's arsenal.
There's no reason Paladin't cant use Cure 2, perhaps modified to do decent hp. I'd honestly accept a 600 cure for 300 mp.
There's no reason (seriously) that summoner (scholar can) can't use cleric stance.

etc etc.
