My group has been trying to hit a certain score in Vet dsa. In doing multiple runs we have had the same issue- someone [usually the healer] - dcs during the graveyard round.
Sometimes, it creates a dc chain. Other times, it is just fine after 1. We have tried different positioning and casting less dots/hots. Nothing seems to help it.
On asking around in our guild, the groups of players all seemed to have an issue with round 5 in this arena. [My groups issue usually arises in. Round 3 or 4] We are on ps4 NA and do not run at peak server time. We usually run between 9am and 1pmest.
