I saw a 3 year old discussion on reddit about which role is hardest to play in current WOW (at the time). I wanted to see what people think now about the same topic.
My opinion is that it’s very different depending on the content you’re doing. For me it goes:
Raid
ranged dps > healer (often doesn’t get included in all mechanics) > melee > tank
M+
tank > healer > melee > ranged
My justification for M+ is that learning the route/percentage is a huge burden that all tanks have to look up on the internet and get tools for (like MDT). Other players will eventually pick all of this info up from playing with tanks, but they don’t need to learn this at the start of an expansion - while all tanks do.
This might be anecdotal, but I also see more tanks start to get into things like focus-kick macros compared to DPS. Tanks can often have aggro issues, and need to taunt a target that is not the one they’d like to kick - so I see a lot more tanks who use focus-kick than I do dps. Obviously the only healers who would focus-kick are shaman, so I’m not sure how many of them are using things like that.
I’d also argue that tanks have the most affixes that affect them directly. Necrotic, raging, and bolstering are really tank affixes. Healers obviously have bursting and grievous. The dps affixes also affect tanks and healers.
I am playing healer mostly this patch. The difficulty seems to vary wildly on whether you’re in a coordinated group or a pug with ppl who don’t care about mechanics, so I could see healer being lower on this ranking for M+ (depending on your group).
