I used to have horrible latency, especially when I zoned. It would take two minutes to re-enter an instance after I had died. That turned out to be a combination of Blizzard and mod stupidity. Mods were apparently updating the screen when there was no interface and WoW let them try to do it, so you'd end up with all these queued interface events to work through. A WoW patch finally fixed that though and it was a blessing!

So why do you reckon your ping times are bad and how bad are they?
