Anyone ''farmed'' ultimate ajax?

[DevRaiden]

So did anyone so far here managed to ''farm'' ultimate ajax and how long it took if you did? cus ok i got lucky with blueprint drop , i am atm farming another part from HM executor , but rest seems kinda impossible almost? walker so far unkillable with random ppl and u cant enter solo ... so you are doomed if u dont have friends to farm it , other option is those reactors but each reactor have only 25% chance to drop sphere that gives 6% chance to drop ajax part ....like wtf? 25% for sphere and 6% of sphere ??? not to mention that for each attempt you need 10 void runs ... so u might do 100s of void runs and get like 0-2-3 sphere and then pray to 1000 gods for those 6%? xD so if anyone did it pls share strat or something i got lost when i seen this numbers ...
