Shadow tag was especially fun for the first few days, but people from other teams using pneuma/healing their opponents Doom Trooper made the whole thing very frustrating at some points. I guess it's fine and part of the fun when competition is balanced, but more often than not you have a team that is much bigger than others and that is enough advantage to win the round in most cases, no need to bother the rival team with half the amount of players. Not sure if there is something that could be done to prevent this since having different houses help each other is common and you obviously can't block skills from being used in a PvM scenario, so this is just an observation.
Other than that, the event has been really nice and the new minigames and hunting grounds changes really help! Great use of the possibilities of the new client to make the event more immersive with titles and special effect costumes.
