Ok so have spent the last 4 days farming out rivals this is my results.
My character is level 31 and 27
I also play solo and have been playing since launch
Have a Total of 100 level 4 rivals killed
14 x Military tanks
18 x fNIX Tanks
20 x Hunters
28 x apoc Tanks
10 x Prototype Tanks
10 x Harvester a mix of all types.
The Total amount of experimental Weapons of the 100 rivals is zero.
in 100 rivals farmed I got no experimental Weapons at all
if this is the path the dev team wish to take with drop rates well I won’t be around to play the game.
I must say i got a ton load of experimental clothing
Please is my expectation too high?
