Encounter Design needs to be overhauled at a fundamental level

[Nedkel]

The ideas look nice on paper, in reality you would have to adjust everything to exclude healers dps from equaction for example in savage mode.

This puts more responsibilities on tanks and healers, thus making those jobs more important which is questionable thing to do.
First and foremost it would decrease the number of players playing those jobs for obvious reason, second is it would hurt the party more to have clueless healer and tank resulting in smaller chances of finishing the run, a tank dying with those changes would mean healer is going to be 1 shoot more often and from here there is a short way to wipe. FFXIV is not Wow where you could increase sustained damage being dealt to players, mechanics are far more punishing to the players and teams, if you put on tanks more sustained damage its going to be a mess. Savage bosses are dealing a lot of damage from auto attacks anyway.

Damage would have to be reduced if you make it appear more often, otherwise you are going to inject frustration into the game, with damage being higher could destroy the balance between damage and ehp of the tanks and healers. Not only that but also balance between tanks as well, as some tanks are clearly superior to others in terms of self defense, healers as well with Whm having no issues with MP would make them healer #1.
