I do farm for gold in OD6. If you refer about wins, in that case no.
I do test at different ranks specially on R7-R6 due to the power involve on those players belong to top ranks or real R7-R6 rankers. My mechs are belong to those ranks on test. Sure, sometimes my kids switch mechs to more power just to compensate the match maker abuse matching with R3-R1 mechs on ranks or power base that are win farmers.
This is what they play with time-to-time modifications to check match maker and output and damage received. According to them, they have been pushed down to R9. I guess they change mechs if that happen to get back to rank.
They play this as well in the other account. They do the same test. They rotate mechs after some but use the same. If they switch mechs, it is related to the players do not belong to the ranks. The same for this, they check the same for me. Later I do collect the fights data. They goof a lot not been that serious player. They just have fun time if play. Barely play my accounts. Sometimes a week or more without been touched. Maybe a day play and play some then passing days and nothing. They just play by mood and desire because they play other games.
I am retired and just grind for gold. Normally the account will show up with no fights.
