I think this question is in scope of the forum chat since this change shipped during the patch. My apologies if it isn't!
I realize that Ben isn't listed as a staff member answering questions, but I'm curious how the overall reception to the randomized instabilities has been. I initially saw a lot of resistance to the change, but I've personally found it to be a lot nicer and even hilarious at times.
For example, I was doing Urban Battleground last night with Mistlock Convergence and as we were trying to capture the courtyard, a tentacle spawned in and contested it! I found it quite funny
