Requesting advice about the GAS

[Kabuto]

Hey fellow pso-world members, I seek some advice from fellow members who have gone through the GAS system already.

I want to try to get the Master Force customization, more specifically the limit breaks. My question is though, is it better to get the AEXP from /R missions or just wait till I reach 180 (currently 121). If so what class is more viable or more helpful for the /R missions? since Master Force can't equip any armor without any customization. Any general tips are also appreciated.
Thanks in Advance.

Acrofighter and Fortegunner are both great for DT/r, Fortegunner and Maserforce are Great for Sacred Stream/R.

you will get the AP faster as a 180, but it may take you a bit to reach 180 as the event ends today.

if u can reach Stage 3(1000+ AMP) u can get really good AEXP from World of Illusion/R. I was getting about 70k AEXP in 10min. Just do Stages 1 thorugh 4.
