Anyone who played the Diablo 4's betas will know how disappointing it was to see how much the action RPG slowed to a crawl when it came out a few months later. Gear upgrades and XP became a grind and experimenting with your build was way more expensive than it was worth. Level scaling enemies meant that you never felt very powerful and there was no value in doing anything but dungeons.

Diablo 4 season 2 is like playing the beta again, but better.

It's the fastest Diablo 4 has ever been and it finally lets you benefit from experimenting with skills and gear on the fly. If you were a Diablo 3 fan like me, this will probably feel like a leap in the right direction.

Don't let the Season of Blood fool you: the whole vampire infestation isn't all that interesting narratively, but it's a great excuse to get a bunch of absurdly strong new powers to play with. Vampiric enemies drop a new blood currency that you use to unlock or upgrade Vampiric Powers. These passive buffs augment your skills like season 1's Malignant Heart gems. I've got five equipped on my Necromancer and she's practically invulnerable at this point. Every skill I use heals me, my skeleton minions curse enemies and refill my primary resource, and I occasionally expel AoE damage that wipes everything around me. I'm not even level 50 yet and my Necromancer is an engine for screen-clearing
