Diablo 4: Season 2 - Nightmare dungeons galore.

I've only just started doing the dungeons, since I've only been playing for two weeks, but so far I'm not a big fan. It feels like there's only a few environments, not enough monster density, and the occasional backtracking is also boring (pretty short though, to be fair).

Diablo 3 has technically even less variety with its rifts, since it's just kill demons until a boss spawns, but it's just packed, and I loved blasting through tons of enemies. Although in a multiplayer session, when one player is just destroying everything at mach 2, and you're just waddling behind them, that's arguably worse (I played mostly solo or some friends, doing public sessions to farm bounties or materials).

The open world events, Helltide or Blood Harvest are a bit like the D3 rifts, just not as many enemies, but still really fun. It's a bummer that you can't just keep doing that, if you want to keep progressing your character.

Getting better Sigils is kind of a pain, since it's just RNG drops. I could easily do higher tier dungeons, but have to wait for them to drop. At least you're kinda guaranteed to get at least one Sigil on your current level I guess, so you don't have to move down. Now that I'm writing this, I gotta check if I can craft some higher tier ones, last time I was missing some materials, maybe it's not as bad.
