Guild Wars 2

After patches my skill lag has gone up every time. (weird that i didn’t have any lag in launch time) My overcharged shot bugs 2-3 out of 5. My kit swap fails hard for example trying to swap to elixir gun for ground target elixir skill 5. I target and press 5 and nothing ever happens. Supply crate has become a major obstacle. The animation is so long that in my screen it shows it has dropped it but when i do dodge i find out it isnt. I have to to drop my versatile gameplay so many skills just wont opperate in WvW. And im not talking about zerg vs zerg where everyone freeze but all the time when theres like 5 players on map. If this can’t be fixed engi is unplayble for me. Any suggestions? tricks?

Im not sure about elixir gun but the other two are quite normal for an engie to suffer through. I do know supply crate doesnt really go off until the end of the animation, so if you are interupted or interupt yourself even if you see the crate land its not going to go off
