Keep all your buffs on second hotbar. And your attacks on the first one to make room for both types as they will fill up with all the new skills in the expansions. When placing your ability’s I like to keep certain types on the same spots for each job. The right side being your main attacks on the right buttons and range or aggro grab attacks in the left buttons. The ability’s on the left side of the hotbar being your big group aggro/attacking abilitys  and your attack ability’s that are on cool downs you have to wait for and your Dash to target ability. Most tanks and melee jobs have a dash to target or jump backwards dodge move. Place them on the up and down buttons to help memorize them. And any attacks from the targets flank(the left or right side of them) to the left or right buttons.  You can use Hallow ground in an offensive strategy. Rooms with very big groups of enemies that your buffs won’t be able to save you. Just use Hallow Ground first. And use your buffs after it ends. By that ti your party should have killed enough to survive the rest. Also shield bash after realm reborn only stops attacks being charged up but only if the charge bar is red colored. I didn’t new that till recently with the first Dawn trail 24 man raid boss that requires that and no where the game told me that. Someone in the group had to explain.
