Raiding at what level? If you don't intend on stepping further than 2-3/8 mythic you can reach your goals later into the season assuming you get a curve soon.
If you are in a guild that wants to try mythic then M+ is absolutely mandatory, even more important than raiding itself. No other activity gets you full hero track items on the first week.
If you don't like it play another game. Not joking. It's such a setback that it's not worth paying a sub otherwise
