I did throw something on the Bugtracker but alas it's been ignored and it's getting worse and no longer confined to one spot.
It appears any form of mass WPvP (raid group) results in crashing of everyone's clients who are in the area.
It's getting pretty frustrating to say the least, especially when it's the only decent form of PvP atm (no CTA, Imbalance within BGs, bad honor rates).
"make bugtracker reports about it".... Such a major issue was ignored when I made one.
