This has been happening since 5.4 got released.
Organized groups of well geared PvPers would camp pretty much every graveyard (spirit rezzer) on the island - even on the PvE servers i play on...
Regardless of where you die, you are taken to the nearby graveyard - as soon as you are ressed, there are ~10 well organized/geared people instantly CCing and bursting you down.
This gets repeated over and over and over and over again, for literally hours.
The gankers do not get any blood coins at all - all they do is endlessly grief and gank at these graveyards, and you are unable to do anything to stop it.
Your corpse is right there on the graveyard, so you are unable to ress anywhere else - all the graveyards are camped, so running in ghost form to a different graveyard will not save you what so ever.
People who are trying to hunt down the rares are usually poorly PvE geared and quite possibly just reached level 90 - so there is ZERO chance of those random individuals ever organizing and successfully combating the well geared/organized graveyard camping teams that even have dedicated healers.
Waiting for these gankers to leave simply does not work - they are there until 4 AM, and i can't wait (got a job in morning) till 4 AM to log in, HS out and escape this permanent graveyard camp.
Not to mention that i want to actually play through the Timeless Isle - and not be 100% lock out of ever seeing anything on the isle because a single death means going back to a permanent graveyard camp.
Only solution a player can do is log on a different character or log out of WoW completely - and that is completely unacceptable, to have groups of 5-10 players completely DENYING any form of playing experience for anyone else on the island is the highest form of griefing.
I got only an hour or two to play during the day, after work, and the only thing i need in WoW atm is the Timeless Isle for my alts - and these jackasses are 100% denying me any possibility to play... i payed 13e for my game time and i frikkin expect to be able to play, instead of being permanently locked into a graveyard with NO POSSIBILITY of escape.
I literally have 2 lvl90 alts who are unable to leave Timeless Isle - whenever i got time to log in and play, these 'tards are there camping and i can't HS out or do anything to escape the grave camp.
One thing is faction warfare and FFA pvp - a completely different thing is having organized GRIEF GROUPS who endlessly camp graveyards just to ruin other player's experience and deny any possibility for playing.
Blizzard needs to IMMEDIATELY implement that as long as you have the "recently sacrificed to ordos" 10 minute debuff you can not be attacked by players who are on the "ordos coin hunt", regardless of their faction.
