lagg during combo and dungeons and combo glitch

Don't know about other people but I get lagg 98 percent of the time I start a combo, get near more then one person in war, or try doing a dungeon higher then ft2. Also this combo glitch that's been going on for a week where you either miss 2-5 hits in a row during a combo or attack groups of people or mobs and no damage or misses even show up should definitely be top priority for the next maintenance. I would say the lag should be top but when does that ever get fixed.

it happens for me that i miss/nothing shows when i sometimes hit some1 in combo and he doesn't have int/ss....i thought its only me but seems that others have that problem too
