Please check the delay settings in your macros scripts (e.g. for loot). It shouldn’t be any bigger than 1000 ms (1 second). Many players have 100 ms (1/10 sec) set as default. This makes the server have to process more data with no benefit to the players. Because there are technically established delays on the server and that means you won’t perform an action faster than those delays. In the worst-case scenario, we will have to kill the characters who create additional useless server inquiries.
