So what I do,I need only launchers and I have atomic,my strategy was without 2xp event,grinding the weapon until level 30 without thinking about camos,so when you reached lvl 30,you pop 1h double weapon xp and then grind again,you should reach lvl 50 more or less,and then you start doing the camos,that for me was the fastest.Of course with the 2xp event is much easier .
Tool grinding method: Hollow Grind: a groove is excavated on both sides of the cutter surface of the shaping cutter and other cutting tools. Because it is easy to process and design, many factories in the market use this grinding method. The advantage is that this grinding will result in a very thin blade, and the thinner the blade the better.
