I joined Purgatory a week ago and I have to say I couldn't be happier.
On the social side, whether you just want to shoot the shit or talk team comps, their Discord is fantastic. Sharing with Unrepentant is an added bonus, where you get fantastic advice from higher level, advanced players. You are never looked down on as everyone is friendly and inviting. Hell even one of the Unrepentant gents mentioned that the Purgatory channel is "where the cool kids hang out".
From a strictly game point of view, for a guild that has no requirements, the accomplishments are pretty exciting. Again, I''m only into my 2nd week (Thursday) and both times have been well over 20k seals (damn near close to 40) all tasks to at least 7 and completing 2 completely and well on our way to a 3rd this week. Again, for a guild with no requirements, there is some serious dedication here.
In short, Purgatory is the best of both worlds for me. A fun, social minded guild that has that spark in them to want to push the guild forward as best they can.
