Atleast we have Warmode now, tagging a World Boss on a PvP server was impossible in Legion due to broken sharding and you being always grouped with 40 members of the opposing faction at all times.
Also, cleared all bosses every week for a year straight in 5.4. - never seen a single one drop (for ANYONE in the raid)
how small is the change? astronomical, and to think I wasted so much time doing this useless shit
