OK I never did get around to putting the build on the test server...but I did get it to level 46. Right now without the purp sets, Hasten is 20 secs off perma and Crushing Uppercut is off by just 2 seconds for the rotation I mentioned. I'm also still missing 1 LotG global recharge. So, I'm figuring with purps' recharges, the last LotG, and Ageless it'll definitely be off recharge for the rotation.
What I've learned thus far though... It's a Boss deleter. It's a different playstyle than I'm used to, just ST rotation, but it's 1, 2, 3, sometimes 4, next target. I dipped into the Teleport pool and use Combat Tele to get into position before my team can scatter the mob, otherwise my rotation switches to using Spinning Strike until I find the boss. I even last long enough sometime to take the big guy out solo then I might have to pop a med purple to smash the rest. Endurance is absolutely not an issue so that got me to wondering...if it turns out I don't need...need Ageless for recharge, which I'll know before Destiny gets unlocked, would Barrier be a better choice for more survivability? Barrier would also work thematically as my Stalker is a science origin that utilized technology, so a force field look is a good look.
On the other hand....
Ageless Radial will boost my debuff resists to accuracy, slow, and perception to levels that will make them almost bullet proof and give me a lil defense and regen resist to boot. But they are already at decent levels.
Nother question... I don't really like the animation of Sweeping Cross and I've gone into the Weapon Mastery pool (didn't know it had a drone!) partly for theme, and right now I've selected Web Grenade for the build...useful? The enhancement set bonuses help but other than that and being as I haven't picked it yet, I'm feeling like I'll never use it. Or it'll be just for the runner or flyer that's trying to get away.
