Preach it!
The most trouble I had with Titania NM was during a run where people didnt understand the simple mechanic of standing in a water puddle with the stackmarker - despite it being explained. They didnt get it the second time said mechanic happend either - despite it being explain again.
The problem with this fight - as with the other MSQ-trials - is never that its to difficult or asks to much... its people who struggle with something simple as standing in a specific spot...
