Agreed, Legion and this expansion have more dailys/grinds involved than any other xpac in wow hands down. To keep your character power progression just on path you need to do daily quests without missing them (no way to get the reward back if you miss it), farm AP, farm visions and then do your mythic/raid content. And if you are a mythic raider serious about progression you will maintain a high level of pvp as well.
