Memento for trial achievement is... weak, boring and shameful. As a rewarding PVE players with RP reward (mementoes are useless otherwise) or as gating RP item behind endgame PVE content - it's just bad.
None of us is getting any younger, you know. Each event is preceded by Prophecy. But without the hero, there is no Event. ...All true adventures include some deep bruises and frantic screaming, right?
Would be a good idea to make vet trials playable before pushing it to the live tbh.
Also would be interesting to know if "new way" of giving telegraphs is intended or not? It's a day/night difference for the ones with low spec PC's and those groups getting bad instances (all of them?)
