Usually everything is good, but once in like 10 games it just happens so I can't use skills fast one after other. What happens is if I'm trying to use many skills at the same time, character just stops processing any commands it receives, like I'm being rate limited. It's not even any complicated combos, just for example using item, skill and click on the ground withing one second is enough to cause problem. At this time also ping doesn't increases, packet loss stays at 0 too. Also I can see what other characters do without any lag or anything. What is it and how to fix it?
