How to unlock the Jack of One Trade achievement in MAG - Definitive Guide
Since 2.0, the skill tree system has been completely changed. The easiest way to acquire the trophy is to fill up entirely one tree, this will cost over 10 skill points. I strongly advise to get the Medical tree filled up first as it's very helpful for you and for your teammates, and it will give you tons of xp.
