What did you just say!? 280 L-M! That's insane grinding! I have played for 2.5 years and just got some few decent items...
I usually farm for 9-12 hours per week, i farmed in OD6 as you said in the old forum because it is good. Sometime i try to farm some fortune boxes but my luck didn't help me much... I also save A LOT OF TOKENS to buy offer and it help me boost my progress in game very much. (sadly that most of the offers came at the times that when i was out of tokens... BRUH)
The best items i have now are Heat Monkey torso and Energy Monkey torso, flaming scope, the claw, L-M heat hook, rolling breasts and selfish graudian.
I guess i have to wait for another 2.5 years to get the L-Ms that I want LOL.
