What's the point in an AP grind now? If you haven't cleared having 1% extra damage on Pyroblast or some shit isn't gonna suddenly boost your rank by 300. Too many people mistake themselves for hardcore and think what the top 100 are doing is what they need to be doing.
Grind yo herbs
Do yo 4 WQs for the cache
Get on them Mythic+ on the weekend
But don't trick yourself into thinking it's necessary for you to do every single AP WQ whilst you're sat wiping on the 3rd boss of the instance or some shit.
