The 4 Piece Sentry Bonus: Insane.

I'm running around now with 4 sentry and 2 tactician (I prefer Striker, but RNG).

After running some DZ, challenges and the incursion, I can safely say the bonus is absolutely insane compared to the other sets.

It's almost as if the set was designed to have the headshots come only from Marksman Rifles. Because of this set, I'm now just face tanking heavy gunners with my healing MP5. The damage output, for the entire team I might add, is hilarious.

The Striker and Tactician 4 piece? Not even on the same playing field. They should get buffs or changes.
