Considering the game is about to be closed, I wanted to go through everything the game has to offer at least once and get most of the possible achievements (some are mathematically impossible, but I can get about 105/133).

How can I quickly get something that allows me to do mutations, hive, catacombs and a bit of PvP (mostly Outpost Rush)? I've heard the faction stuff isn't that great, which was my first thought.
Ideally an Int build since I want to farm Hyssop in the meantime to level my Territory Standing (I want to try getting at least one region to 300).
