you will need to farm around 1750 JTs a week to keep up with max ranks using 195 mods.
I constantly swap the following mods depending on the mission: Remote Detonation, Radar, Radar Jammer, Flak (majority of the game), Fragile (for CQC shotgun combat), Car Surfer, Blowtorch.
For a low level playing a few hours a week, that's impossible to get through normal missions since low level contacts give very few JTs as a reward. It gets easier to earn JTs on the rank 195 and higher contacts, but by then you can just buy the mods off the market.
FC is an option but not everyone enjoys the chaos.
The contacts also give out vehicle unlocks, sprays, clothing, and can still hand out a free mod and unlock the ability to purchase additional mods.
The only thing that needs to change is the rank requirement so newer players can purchase them on the market board.
"Progression" by leveling contacts is not the only reason people play this game. I've been maxed out for years and still play APB. Most of us here have been maxed out for years and still play, why do people think "progression" is the only reason people play?
Let the newer players have access to rank 195 mods, they change how the game is played completely, there is no need to drive players away because they have to play an unfair game against us vets.
