... aw mannn lol. Well I guess I'll build Elise up anyway lol.
The main reason I don't like the new mode is how tedious it is to play. 15 energy to play an easy (oh sorry, "advanced") level then get, I think, 12+ hearts to a random unit, then getting one tiny reward like every 15+ plays of advanced levels (someone on reddit mentioned that they only 4 orbs with a 14k score). I agree though if it wasn't FE:A I would like it more lol. When can I bond with Ephraim :'( Tl;dr it's a grindier version with less rewards of Tempest Trials, and I would rather be playing Tempest Trials.
Also this summary of the FE Heroes Part 2 story is hilarious
