Don't get me wrong, the new league is super fun. But! There's a lot to improve. What I've noticed so far:
1. Decay speed and mosters are kinda overtuned in the beginning. That's ok as a softcore player since it's a learning experience and it feels nice to start clearing the memories, but as a HC player I would be pissed.
2. Monsters shooting from 3 screens away with fast and deadly projectiles - this is just insane, especially for slower characters early on.
3. Monsters waiting for you right at the start. Nothing is more fun than starting a level and instantly seeing 500 mobs and projectiles fly in your face.
4. Fast decay, instant slowdown. Decay seems to sometimes spawn right on top of you, giving you no time to react due to the instant slow. This is especially frustrating combined with 2 and 3.
5. Random decay, unclear pathing, unclear directions. It is enormously frustrating to run through several carefully planned memory tiles only to have your goal tile be ruined by sh*tty RNG: Running to A, seeing the path blocked, running back, seeing the path blocked, pathing around, seeing the path blocked, flamedashing over it, running to B - dead end, running to C - dead end - looking at the map like "where the hell am I supposed to go?!" - running to D - time is out and apart from a few minor drops on the way, you just wasted your time and tiles.
