The majority of people saying there's no problem seem to make the case "I can avoid it, therefore everyone else must be bad."

It's weird that you can be good at split-second reactions yet lack the perception to notice all the very real problems the OP is talking about.

I dodge everything. My FC is done with Turn 4. I am very good at this game. I also notice and acknowledge the massive coding lag, poorly synced spell/cleave animations, delay in other player animations, constant "you are too far away" messages on moving targets unless you're half a foot in front of the mob, etc. All of those problems exist, as well as the "instant abilities are only instant as long as you don't interrupt a precious attack animation" mechanic. Makes interrupting things really fun.

Overall, the responsiveness in this game is garbage, and if they release PvP while the game is in this mechanical state, it will be the most widely criticized and laughed at attempt at success since Diablo 3.
