Hot take: I think some Ultimate mechanics are easier to resolve than Alarm Pheromones.
That mechanic is absolute trash for anyone with any ping above 100ms. This concept of 'ping' seems to be foreign for the devs, and some players apparently too.

Speaking from experience. I get weird situations where I get knocked into a wall because I was only human and didn't perfectly estimate the width of that bee attack from the other side of the arena. Someone with a low ping might estimate it approximately and they can do a micro-adjustment the moment that the AOE shows up for that half a second and they're out of it in time when the actual AOE goes off. But for me? That line AOE shows up, and if I'm in it, even with a single pixellated pinky toe? I'm already snapshotted in place and will be sliding into the wall before I even see the actual mechanic go off. I can sidestep all I want in response to the initial AOE, doesn't matter. I have to do it right without any microadjustment. No adjustments, no second chances.
Don't get me wrong, I've done so for weeks now. It's still a frustrating and unfair mechanic for anyone with some distance to the server and I'm happy I can just skip that fight these days.
