Inc rocks and it is boosted by Mordeo/Primarch.
It depends how purest you are, but I have a 6in1 Inc which isn't far from perfect and given the Inc isnt the best in PvP due to its speed, it depends how important this is to you. You could trade 1 Blaze for 2/3 Lacerto perhaps and make a good buffer?
I am running Um - Mut- Inc - Prim - Um (to be replaced with 2nd Inc) and i like it.
