TCG event was mostly fine, really didn't care for the ending. All that mystery and it's a bunch of stupid Treasure Hoarders? 1.3 all over again. I don't like the TCG, but at least the event was only themed and you didn't have to play much of it.
I normally like the events with the bosses and all their buffs, but not this one - I just really hate the Thundering Manifestation.
Domain builder was eh. Never cared for events where you can't bring your own characters, or they're extremely nerfed, and it's not combat- or story-focused, so...
...surprising absolutely no one.
