Been wanting to try one of these for a while, but finally got my DB/SR stalker to 50 and began slotting. Right now, I'm softcapped defense to all positions, running about 147% global recharge and have several high cost sets slotted (still need about 400 mil more influence to finish). I can almost run AS-Ab-SS-Ab- but need to get my recharge up to around 170% to do this seamlessly. All I can say is, this character is a blast. The damage numbers and speed that it throws out are unbelievable. Survivability is good, but hampered currently by low HP. I'll need to get some of the accolades and finish slotting to bump that and regen up. I've also been running the melee Hybrid slot that focuses on regen/resistance and that has made the character much tougher. Other issues early on were endurance, but proper slotting and the ageless incarnate have pretty much gotten rid of this. This is shaping up to be one of my favorite characters and I'm glad I've found one that I want to devote time and energy towards.
