Been doing solid 400+ games with it so far so long as my team does their part. Really really runs well with an ecm mech. GRF-3M "Freedom's Claw"
Artemis still helps speed up lock time with streaks, and doesn't cost any tonnage with streaks like it does SRM's or LRM's. Always worth the additional cost to use Artemis with streaks as you get a benefit with no cost other than the cbill's spent.
For now they work with streaks, but pretty soon they will not when they get fixed per Paul's post about Artemis changes. http://mwomercs.com/forums/topic/142915-a-rework-to-artemis/
I run a VERY similar build with great success! I have a slightly slower engine at a Med Pulse. I stick with the group and focus on an enemy mechs rear or weakend spots. Fry the armor with accurate Pulse fire and then pummel then with 8 Streaks. The BAP and 4x SSRM2s help me deal with fast lights.
