You are right, and I fail at feeding the Troll. This is the only issue other then only 4 bosses in Coil that I have with the game right now. it is rare but when it hits ya it sucks. haven't gotten hit by the knock off ability with the lag but the plumes have gotten me when I am clear on the other side of the platform.
But Titan is the only fight I get this so I can't QQ too much. Coil has been fun we cleared Turn 4 last week and Turn 5 looks to be fun, so overall the game has great content. I like that SE has addressed it and is probably working on it if they can. maybe they just need to add more data centers. Having just the one is prob why some people lag more often if they are farther from it then others.
