Mastery

[RAmh]

id say leveling after forma should add to mastery too,some weapons require a lot of forma and a lot of time,some frames were releveled 5-6 times and its painful

With 20 formas sitting in my inventory, i can't imagine what rank would i achieve should i decide to forma my warframes, it would make ranking pretty easy and bad deal for DE as slots wouldn't sell.

The fact that it's painful is the price you have to pay for a polarity slot.

You know, you don't have to forma everything, right?
