Nothing in the upcoming patch notes that I seen addresses the fact that in large battles, or even medium battles on full servers, you can not see almost any graphical effects. There is no way to see if you are in black talons, if you have the blue silence dome over you, nothing. You are basically guessing what is happening and doing the best you can.
If you want to keep the entire system 'que based' then you need to make it a priority and fix it so that it works in PvP, until then add the ability names and buffs/debuffs back to the api so we can figure out what is going on and you can remove them later when your que system is fixed.
