welcome back to the game!
well, asking what you missed...
1. CC damages had been fixed (refer earlier reply)
2. homunculus nowadays are nothing more than glorified pets that can cast skills (you need to manually active the skills tho...)
3. Meteor Assaults and Magnus Enormous (just typing, dont really remember the word LOL) are now so hot...
4. OCP sale had just ended, so if you got some extra zennies there are some eq you'd want to get your hands on that quite cheap
5. lighazen biolabs are now in the heat.. pretty sure its hard as f... >.<
that sums up most major gameplay related latest update i guess? IDK..
