Keyboard lag killing mood

Doesnt matter if its default key bindings or custom, my keyboard imput is lagging. i can bind it to my mouse but i dont have a 20 button mouse to key everything to nor do i want to use my mouse for everything. cant use potions on time or at all. cant evade properly. takes forever to open the map/inventory/skills menus… since patching out frequent disconnects, the game has been ify for me… dont even want to play my rogue anymore because im dying from not being able to play at its best. using too much gold to repair items from dying. just selling or salvaging all since i dont feel like using space to junk things. one full inventory takes about 3 minutes to mark everything as junk. waste of time playing if this doesnt get resolved.

Is it keyboard/mouse lag, or server lag?

When you press a key for a skill, does the skill show as pressed on your skillbar, but nothing happens in game?
