With the feedback from the test servers devs had enough feedback about the dcs...
Having said that, devs please don't release some content just for the sake of it...the game is highly unstable
I tried running the tombs 5 times so far and each time at least one member of the pt dcd. You need the fix the dc issue that has been existing since the start of Halloween event.
Probably if the servers are overloaded due to the particle effects of the para stone then remove those effects if it helps.
Its just plain annoying when you spend hours trying to run the tombs without even completing one run.
