This may be kind of off topic, but...what is the best way to level up say an AFK S/L Tank build assuming I have no other assets on the server? How do I get it to the point where I can actually start surviving on the designated farming map itself? Money doesn't seem to be an issue so far (making 1.5 million Insp per about 15 min farming on the Bads in Space map but the Exp is SLOOOOOW). Thanks in advance for your assistance.
