This is more of a suggestion to players than ArenaNet – if you’re looking to do the Mordrem Invasion events for fun rather than to farm the blooms, then I recommend that you don’t try to follow the commander tag.
I’ve managed to do a few events, albeit you get less blooms, but when a commander tag is not around, I get more fun killing the Mordrem, the event is harder and there is little to no culling!
I’ve even gone so far as to not travel across the map to find events, just casually wait for them to arrive nearby, so I don’t end up wasting money on waypoints. Here is a picture of my character Tony anticipating another Modrem attack in Kessex Hills.
