Rn routing isnt issue at all . It was back in days, nowdays u need to pull everything anyway.
I remember back then when we had that stupid pride affix, where u had to hace 20-40-60 etc % before each boss or big pull, that was for sure a routing issue .
What they should do, is make dungeon especialy trash a less mess . Holding W and going forward isnt issue. Knowing which mobs are dsngerous who do what and how to countrr is , that is. U cant pull 2 packs of caster mobs most of the time especialy with ranged group, but then there are pulls where u can pull those mobs in 3-4 packs and its okej, and thats what new tanks have to try and do, they either fail or it works .
This brings 2 issues. If they dont do anything and tanks will simply try and find out people will be even more toxic ( altough i dont see many toxic groups , or not as much as those forums make they seem, even if we dont time) .
Second issue is , if they do change trash and made it significantly easy on tank ( and their knowledge) then more experienced tanks will be able to pull half a dungeon …
And then on top of that there are people themselves, they cry there are no tanks , but when tanks are in good spot then they cry they do too much dmg , or they dont need healer etc etc .
And then we have raids, where u need 1-2 tanks for 20, or even 30 man raid, u ecer tried to get into a semi serious guild as tank? Impossible realy , so its better to just sticking as dps.
So yea, not realy much that can be done , without it backfiring .
What realy should help, is , adding some extra reward at end of dungeon , but not loot, that wont fix anything .
Be it gold , like 3-5k , those augment runes, satchel with mats or whatever. Even random cosmetics will do , maybe some kind of coins or whatnot where u can buy some extra cosmetic after X runs .
But even that would lure just a few it wont make much difference, imho
