Heavily depends on the people who will be cast as new GMs tbh, if your only reason is 'we need more so let's get Randy McRandinston from IT' without strong reason then you risk the same loop imo.
And, in all honesty, some of the GM team is fine, I've talked to a bunch and I've gotten responses at a rather normal rate. Sure sometimes RL can get in the way or whatever but they're human too ya know, they can get burnt-out way more than us who don't religiously have to follow SL2's everything, and they for sure don't deserve being dissed behind people's back.
And for the record, change doesn't always need GM input I guess, most of the time sure but uh... you really think players can't help with minor stuff too for new players?

In conclusion: Not all of the GM team is incompetent as they're doing their best and they deserve atleast one or two 'hey guys nice work' every now and then. and if you do get fresh blood, make sure it's not some clique, make sure it's someone trustworthy not to regret casting later on. Although I don't think there is any hurry for new GMs to be had since, yea, players aren't really brainlets who sit and watch people who want clarifications on what X in the Y tab does in battle. GMs aren't the end all be all for the playerbase support- I don't mean any offense by that just, yea, they're not powerless as you think.
