You need to READ what the OP wrote more carefully.
"Sheltron & Holy Sheltron & Intervention.
Request:
Combine Sheltron and Intervention into one hotkey.
Using Sheltron gives you the buff, using sheltron on a party member gives them intervention.
(same as Gunbreakers Heart of Stone)"
So I say again with further explanation.
Paladin:
Holy Sheltron - Intervention
Gunbreaker:
Heart of Corundum - Heart of Stone
Dark Knight:
The Blackest Night - Oblation
Warrior:
Bloodwhetting - Nascent Flash
These ALL use separate skills for a reason. So that the each have unique buffs/mitigations. You think it would be wise to let WAR put bloodwhetting on other party members.....of course not. This is why Nascent is just a heal when the warrior attacks....not the other way around.
This is why TBN pops and gives boost damage to the DRK...not to the person I used it on.
And this is ALSO why Paladins intervention is completely different then Holy Sheltron when you read the tooltips. Fusing them together would mean making the skills the same....which they aren't.
I would like to add that Heart of Stone is in no way shape or form even close to Heart of Corundum. Heart of stone is just 15% flat, and also gives Brutal Shell heal to party member when used on them for 30 seconds...which is like 11-12 brutal shells. Heart of Corundum adds to Heart of stone by giving another 15% mitigation for 4s initially (total 30% for 4s then to 15%), but then also adds a 900 potency heal (which is basically an essential dignity at 30% HP, or Excogitation might come the closest) when you either fall below 50% HP or the duration of the effect ends. When you use it on another party member they get :
Flat 15% mitigation. Gunbreaker or party member
All Brutal Shell heals also given to a party member. Heart of stone only does bold text
Further 15% mitigation for a total of 30% for 4seconds then back to 15% for the rest of the ability duration.
900 potency heal when they fall below 50% HP or 20 second duration ends. Heart of Corundum does bold text and italics
