I'll say it. i was incredibly underwhelmed.
Phase 1 takes how many weeks, phase 2 takes 15-30 minutes and quite frankly it just felt like a regular invasion with how fast we killed everything imo.
Then everyone in the game stood in front of alsbeths portal just waiting for a big boss battle. She finally spawns, they say some words, then its over. Went in the raid with a 20man pug, wiped twice on the first pull and called it a day.
Coolest part to me is this was put out a month after release, and im really looking forward to future, better events.
