With warriors essentially becoming juggernauts now, I think it's time for the PLD to get some love. I'm going to post some suggestions for 2.1 that I think the PLD needs very badly.
Paladin abilities:
Sword Oath -Decreases enmity generated greatly, while slightly decreasing the time between auto attacks.
Cover - protects all party members within range, duration has been extended to 10 seconds and redirects the enmity of all enemies within range towards the paladin. Damage redirected has been reduced to 50% and now includes magic damage.
Gladiator changes:
Shield Swipe - Increases enmity. No longer on GCD.
Awareness - Due to the broken/worthless nature of Awareness, the skill has been reworked. This ability is now a group buff, that nullifies all critical damage from the enemy.
Bulwark - Reduced cool down to 120 seconds.
Tempered Will - Removes all debuffs while preventing knockback and draw-in effects.
Hallowed Ground - Buff is applied immediately after activation, not after the animation has finished. Redirects all enmity to paladin for duration.
I think this will give some of the worthless abilities we have much more use in all combat.
