Thoughts on PLD/GNB/DRK

[NeoDivinity]

Suppose a hit is coming in for 70% of your MaxHP and you're at full health. If you prevent 30% of it, the net damage is 49%, bringing you to 51%, and your Catharsis will probably be wasted as you're healed to full. If you were to block 20% and 10% in my hypothetical, with multiplicative stacking your mitigation is effectively 28%, so the net damage is 50.4%, bringing you to 49.6%, triggering Catharsis. With my earlier numbers, Catharsis heals ~12k out of 72k (~16.7% of Max HP), so your HP lands at 66.3%. If you time the same hit poorly as HoC currently is, with 15% mit and Catharsis triggering you'd still end up at 57.2%. The 30% mitigation is actually the weakest of these three scenarios. Similar to TBN's problem with %mitigation, HoC's maximum benefit only happens when you're guaranteed Catharsis will trigger. In the edge case where you're below 50% HP so Catharsis will trigger automatically and the heavy hit will be reduced by 30%, you'd probably just use Bolide instead.

I agree upon some points buuut....
May sounds good taking your hypothesis as truth but TBs does hit not based on HP nor hit for only this low amount of damage to only take 70% of it, they hit waay higher, thats why you have to put in most scenarios a 30% or 20% mit on top of the HoC/Holy Shelt/TBN. Catharsis it is a neat resource but works as a backup for what i feel on the job's gameplay.
If youre talking about dungeons and normal trials then timing or not the new cd serves no purpose, just like the new Warrior oGCD AoE is only effective in dungeons and casual content, the new mechanic of timing the cds properly is only useful on savage/future ultimate contents.

Briging it from 15% 4secs to 20% 8 secs would make it super strong. you already get 100% of benefit from it Catharsis proccing or not, because you'll get that heal regardless if the times run out.
You also have to remember that not every time you'll have a 30% mitigation to put on top HoC, sometimes all you have is a 20% or even a reprisal. Also Off healers and team mates tends to also shield or mitigate TBs in some cases and Bolide will only be avaiable once or twice per encounter.

From all 3 tanks i dare to say that the only quick cd that is lacking some buffs is TBN wich does not provide any survivability at all and if it does not break you also lose damage, while Dark Mind can be useful this savage tier on most cases its just a useless cooldown that should've been reworked long time ago.
