It's common knowledge that JDGTR does not pvp well or even on an active shard.
I believe he may be running around on one of the Asian shards?
When was the last time JDGTR popped in and spent thousands of dollars buying everything in sight and then disappeared? Pretty sure I recall it was about 18 months ago.
He will be gone fairly soon but before he goes we will all benefit nicely from him throwing around a ton of gold on our items knowing that they wont even be hurting us as we pvp.
Kinda like trading your star player in sports to a losing team that you will never have to play anyway
