Im not sure about the adds but for bosses if the dps' were doing enough damage (Might or Percision) the strongest one will get aggro before the healer. However if none of the dps are doing enough damage then healer will most likely get aggro regardless. Its also like that for raids and bounties. If the tank dies or drops aggro, the best dps will be targeted for example in FGSE Zeus will lunge the dps that's dealing the most damage before any of the healers if the tank isn't broken out right away. In Patchwork if no one is doing enough individual damage to a bounty then the healer will get aggro if there is no tank in phase. This is before the change of course. If it even had anything to do with that.
Update: PS/PC worlds will unlock momentarily. Xbox and Nintendo will follow probably within the hour.
It takes a little bit for me to change characters on EUPC, so maybe the traffic is just huge with how many players logging in right now.
@Mepps there seems to be connection issues on both PC and PS. My launcher gives me errors, and doesn't let me go on characters IF I get to character selection (disconnects almost immediately)
