Augment runes as a BS consumable are close to making me quit raiding there 500g a pop on my surver which equates to 15k a raid night if you average 40 pulls and use augments on 30 of them. I can't afford to spend 30k a week raiding when my cash stack is bloody 4k and my options are to either buy wow gold for irl money or be benched.
Now you might say dude its 325 intelect thats barely any dps who cares don't use them and I'd completly agree with you. I'm sure mythic guldan is killable without augment runes and that my BIS legendary that increased my single target dps by 30k is far more important than rune usage. But as long as they are in the game they give elitist raid leaders the oppertunity to make them mandatory and if you don't augment every pull your letting your team down and will be ostracized for not taking raiding seriously.
An easlily fixable solution by either
1. remove augment runes from the game
2. give them sources other than lfr that nobody wants to run
3. Make them craftable with inscription or enchanting
4. Make the buff not losable on death like flasks
5. The WOD solution of a reusable quest item that you have to earn and then its unlimited rune use
As long as there is a way to increase your dps even if it is minimal high end raiders will require it. Making guldan/elisande progress cost 30k a week is ridiculous and is ruining my enjoyment of raiding.
