I basically never have lagg issues (only in Dalaran and Wintergrasp). I play with Leatrix Latency Fix, which takes my average latency from 100 to 40.
However, whenever I enter a rated arena, I get delay. The game isn't as quick as it is in other places. What can I do to counter this? It really does delay my playstyle quite a bit.
Same has happened to me lately. But only when I play on EU-Cyclone with my warrior or priest. the BG has crashed like... 4 evenings the last week? My DK on EU-Vindication has much less lag.
