Honestly, the use case for this is minimal.

In fact, especially in solo, the chances you actually see this ability get good use is slim to none, especially in this meta where you see massive amounts of damage up front with high levels of sustained as well (sam, drg, mnk, repear, ninja, mch, blm, smn).

Even when you have a perfectly coordinated Guardian, it still requires the paladin to sacrifice more than what they gain, as it usually takes two players out of the fight, rather than one, and eating AOEs is just common place in these team fights.

I'm going to stop rambling, and just say it.

Guardian should give the paladin 75% damage reduction.

DPS classes would scoff at that, but let's be honest, Paladin is a mediocre tank.

Any other tank, or any other class can fill the paladin role, and you'd see an easier fight overall.

Can they be annoying? Sure. Can they chunk a third of someone's health with a perfectly timed Holy Sheltron, shield bash, confiteor combo? Sure...

Can anyone else do that without having to rely on such obnoxious timing mechanics and without long cool downs? sure.

Maybe the name of this thread should be "Paladins are a mediocre class".

I enjoy mine, but let's be honest, performing at top levels of play with a War or Drk is 10x easier for the effort/return value.

At least make Paladin be good at defense outside of the memable LB they have.
