I enjoyed the GaussHunch, with an XL it had either 80 or 90 KPh with 2 or 3 tons of ammo and 3 SL. Havn't gotten it since XLs repair cost went up, but it should still be viable.
I'm still waiting for the Jaegermech and optimisation. I had over 30 FPS when there were 200 people online, but as of late I've been struggling with 10, and normally over 2k online. Hopefully the 9th will bring me back up to at least 20.
