I am always reminded of the car racing training exercise of consistency where it is understood that pushing for the maximum is inefficient and burns resources needed later.
So apart from this sometimes relevant factor of personal energy level and resulting mental focus, is it actually faster to gather large groups of trash mobs? Because so often I see tanks do this not really/only because they are good and/or high item level, but in a messy way, and this results in the healer having to burn through mana quickly and being not at all compelled to do some damage, too, and also, for some classes it must be very annoying to not be able to nuke a focused target.
If you focus on small groups, you can nuke the hell out of them without much worry about your damage mitigation. And this keeps the stress level down, your energy level up, and before bosses the healer doesn’t have to sit around with the group and reg mana, or in even worse cases, cause a massively time-wasting wipe because the boss fight begins without full healer mana.
So, did someone actually do the scientific-empirical math on these matters?
Prompt for this is that today I did four mythics for the weekly, as a healer, and it is extremely rare, I think I have only done 1-2 mythics ever before, in BfA. And the first run was a pushy tank and I thought I’m not gonna last another three of such runs. But then a different tank, same dungeon, and it was like a totally different dungeon experience. Small trash groups, one at a time. The squishy low-ilvl warlock (171K health) was suddenly a survival expert instead of dying several times on the same boss. It was so nice and relaxed and a generally pleasant experience with some chatting, loot sharing and joking about minor mishaps.
I also suspect that the forced manual grouping inherently makes things more personal, deliberate and thus more like the oldschool style. - And you also have a choice in this, because you can read group descriptions. I saw “rush” ones, but I chose a “chill” one and then continued that style, and others appreciated it, too.
P.S.: Where can I actually conveniently see a player’s item level instead of relying on the hitpoints? Maybe some tiny addon simply showing me this somewhere else? How can the char inspect frame not include item level? - It would help with understanding the game better and judging things.
