I just rolled Frostmourne with my bro and currently leveling with around 350-450ms.

Sometimes will face up to 1k but for a short period of time.

Dungeons are fine, raiding not too sure never done yet in frostmourne.

Nope, I'm not using any tunneling services. Just the RM88 streamyx line. Furthermore playing on WiFi and 2 comps WOWing at the same time.

Previously I play in Gorgonnash, about the same latency 350-450ms pvp, raid. But sometimes I'll get dc mid raid and I can't connect back until they kill the boss. Too much data I guess, loading screen then DC out.

ROFL, I need gold too. Been questing like a mad mofo. I know gold will come once I can chain random dungeons and vendoring craps at level 80.
Sigh, dual spec, flying epic, professions...
