I just tried to play after about a year, and my latency is so high I cannot do anything. I'm talking 10-15 seconds before potions are used. In the past, that bad of lag would have DC'd me, but now I'm stuck sitting and waiting on things to happen.
Relevant tech info:
Bera
208 Cannon Master (it happens with potions before I even go to a map and use skills, so I'm not sure this matters)
Wi-fi connection, ~150 Mbps down
Windows 10, haven't gotten the most recent feature update yet
Steam launch
I would list my specs, but the game is running fine, it's just latency.
