The fact that I have 999 Seraph Crystals and they went and removed all the items worth buying, forcing me to fight a raid boss for a chance he'll drop what I'm looking for is definitely one of the most annoying things they've done so far.
Seems its because they wanted to make certain items hard to find, but really all they did with this is annoy the players.
Tbh most seraph items are a novelty at best. Meteor Shower, Evolution, O-Negative, Hawkeye, and the Infection are basically the only good Seraphs. Most of those now need a Guardian kill to recieve. Getting a good EVO or O-N is going to be horrible.
What is a man?! A miserable little pile of secrets!
