Very good post. I'd forgotten that I didn't include the ability to get energy from my dot crits. Running into energy issues recently... Time to go fix myself
Also, as far as snipe and ambush are concerned, you can drop an exploding probe on them just before it hits for a nice big surprise. That's not doable with cull or series of shots because it would cancel either of those two. Nothing like watching a 3rd of their life vanish in an instant.. Then again, I've not hit 50 yet (only 49). Maybe I can get it to hit harder once I get geared up.
