I think positive feedback is quite a rare around these parts. If devs mess up they get told so(as it should be), if devs do something good, well, silence.
Zariel easy mode is a good addition to the game ! Great job ! We really needed an easy enough trial that could be done with almost no prior knowledge or training and it hits just the spot. The fact that it drops comp gear is the cherry on top.
Now for the criticism part: Tanks have to know when to swap aggro and it is not explained anywhere, maybe add a lore entry in battle tactics when people wipe, explaining that when a tank gets stunned and zariel kneels, the other tank should hard taunt.
