Hey everyone, we've made a few adjustments to how tapping rules work in Legion, which you've probably already noticed, and would like to get some targeted feedback (and bugs).
Most creatures you'll encounter will now allow up to 5 players on their tap list by default. The mob's name will grey out when you can no longer obtain credit for attacking it.
Parties are a special exception, as we allow your entire party onto the tap list if one person is on the tap list. Please let us know if you find bugs with this, we want you to be able to progress with your group.
Rare spawns, world bosses, and quest bosses will largely continue to allow unlimited tappers, as they have been previously, both to facilitate large group engagements and to remove potential roadblocks.
As someone who recently went from five to eight accounts, the party exception caught my eye. It seems that theoretically at least, it's possible to have up to nine taps on a target: a target can have up to five taps by default, but if four taps are taken and the fifth member is part of a group, all party members will be added to the tap list as well - thus allowing for that theoretical maximum of nine.
