Suggestions: BLU Spell changes for the Tank Role

[Ravenguard]

Sounds good, but I wish more would be done to encourage using cactguard instead of BLU tanks being Diamondback bots...

I was wondering how to address Cactguard.

A lot of the tank busters in ARR didn't have cast time, and in HW they were very quick. Without any changes to BLU's passive mitigation, if they allowed Cactguard to be cast on self, it seemed like BLU Tanks would be expected to rotate it every 4 GCD to make up for inability to survive fast damage spikes (outside of Diamondback).

Maybe extend the duration, and give it a cooldown? (I feel like would just be reinventing Rampart lol)

You aren't far off with rotating it as a cooldown, formerly Inner Beast on WAR used to have such a role, a (damaging) GCD action that provided -20% damage taken for 6s. Tankbusters in ARR without cast times have been dealt with by learning the attack pattern (ex: Titan - Rock Buster (frontal cone swing) -> Mountain Buster (frontal cone earthquake)) and using mitigation ahead of time.

But there lies a big problem due to Diamondback existing:
- the damage penalty of Mighty Guard (-70%) is too severe to encourage any damaging actions over using Blood Drain until you have Diamondback ready and letting your BLU healers do the extra damage instead
- as you said, it requires a 2nd BLU tank to actually use Cactguard on the MT to make any use of it.
