WoW is a CPU bound title, not going to see a massive improvement, if any, from a new GPU. In towns and in raids/dungeons it is all about calculating player position and spell/damage/effects, all which has to be transmitted to and from the server for everyone in range. GPU just does the pretty graphics.
Back in the day I got 144FPS with a GTX980 at 1440p, stopped playing after Draenor, but was still getting 144FPS at 1440p pretty regularly.
CoD what? I can't imagine a 2070 only getting you 132FPS at low...
Quick check on youtube, Warzone at 1080p high settings with a 2070 Super was pulling in average 147 FPS, at 1440p 112FPS. Might just be worth it for you to crank the graphics up. I have seen a few inklings that the game has issues...
