Hard time deciding between wow or oldschool

Hey guys, been having a lot of trouble deciding whether I should play old school, wow or both.

To give some more info on my accounts and where I am at on both games I'll list some info below

wow- 930ilevel druid,14k achev points, a couple other 110s that are lower level. I am very familiar and comfortable with the game.

Runescape- 2170 Total level, Achev diary cape, full favor in all the houses, all buyables leveled to 99 except prayer, 50m bank(Had a restart earlier in the year). Huge goal is to max, always been a dream of mine.

I do have a dual monitor setup allowing me to play both games at once.
As you can see I am fairly invested in both games, I do love both but feel like I am wasting time trying to play and main both games when I have school/28hr week student job.
What would you guys do?? I've always wanted to max on runescape and I love skilling/bossing on it. But then again on the other hand I love arenas in wow(Play at around 2200 in 2s) and I love grinding achev points/mounts.

TLDR: Really like both games. Want to max on oldschool but like wow graphics and gameplay, invested a lot of time into making good accounts for both. Have dual screen and capable computer and want to hear ya'lls thoughts. Thanks!!

 

Can’t really attest for WOW as I haven’t played it much.
Never could get “over” my RS love.
So imo, I’d stick to RS. At least until you max. Then once you max, you’ll have achieved what you originally set out to do & can then continue bossing up on WOW.
