So there is always an argument about utility and dps. I dunno this might have been said before. If not here I go.
Let's look at ranged for example. Let's eliminate all utilities from them. Then give them 3 role skills they can only choose 1 of. 1 would be a group def buff, 1 would be a group attack buff 1 would be emergency heal , regen type. You would prog with def and heal buffs and since all the range can us it ,no one is preferred over the other. Then when you start hitting enrage everyone selects dps group buffs and boom.
How would we differentiate the classes? Easy make every exact class have the exact theoretical dps limit. Let say at pure optimization with not buffs you can hit 11.5-12k. All the classes can meet this limit. What makes them different is the skill level needed to get there. BRD would be the easiest of the 3, with a low APM and low skill cap, DNC would be medium and MCH would be maximum sweaty. The pride comes from not only being able to reach the theoretical cap (minus buffs and pots) but from mastering the class. A MCH who cleared Ultimate is much more BDE than a BRD for example, sure you can clear it with a group of easier classes, but real recognize real right? If I see you cleared with a MCH I know you are dope by virtue of how hard the class is to use. Like I said, real recognizes real.
Before anyone says, well not everyone should be able to do all the content, I mean the limiting factor is the player. If they suck they suck and wont be able to reach the theoretical cap and beat anything. Savage isnt particularly hard so it has no effect there and no one gets into ultimate shit so maybe they would, and those who clear it with the harder classes know what's up. Hell beat it with a BRD and then master it with a MCH, it would make people try different classes once they reach a skill ceiling.
Just figure out how to apply this mentality to casters , tanks and healers. For casters remove the group emergency heal with and emergency raise? Casters would be top DPS in all categories because on top of potential hard APM and rotation they are turrets and ,I belive that skill is worth the damage.
I'm kinda spitballing and would delegate the nitty gritty to the sweaty speed sheet warriors to figure out the potency numbers etc and dots.
