Night Widow Smoke Grenade

I've been customizing and rebuilding my Night Widow for some time now, but i've been having trouble evaluating Smoke Grenade. There have been some changes to the manner in which the power functions, but i'd like to know what others have gathered through their testing.

It was my understanding that originally, Smoke Grenade required a ToHit Check to apply *both* its Perception and ToHit Debuffs. Patch notes indicated that the ToHit Check was removed from PvE for the -Perception, but the power still required a ToHit Check for both effects in PvP and for the ToHit Debuff in PvE. The problem here is that the in-game ToHit Check details specify something to the effect that upon using Smoke Grenade in PvE, one applies both the ToHit and Perception Debuffs automatically upon use.

Additionally, the in-game power information states that the -ToHit Debuff is unresistable. If the in-game description is accurate, there is no ToHit Check for either debuff in PvE and Smoke Grenade is a decently powerful unresistable debuffing tool. My main question is this: "What really happens when I use Smoke Grenade now?"

Is the ToHit Debuff really unresistable? Is it possible that it truly is autohit in PvE at least? And if so, are people *overwhelming* undervaluing the potential of a relatively fast-recharging, fast-activating, unresistable ToHit Debuff? Is Better Off Ted yet another comedic joy gone too soon from this world? Any thoughts out there?

I meant to include the foundation for my inquiry. The unresistable information is from the in-game power details.

The in-game stats lists an *enhanceable* Base 3.75% ToHit *unresistable* Debuff. With all that said, i'm wondering if the power is working as the above information states. If so, i'm all for the power. It's just that it becomes a much more potent power than Fire Control/ Smoke or Devices/Smoke Grenade.

For PvE Comparison: (From City of Data)

Power: Dominator/Fire Control/Smoke
Cast: 1.17 sec
Recharge: 15 sec
Endurance: 7.8
Range: 80ft
Max Targets: 16

Perception -0.9 for 60s (auto-hit)
ToHit -3.75% for 60s (auto-hit)

Power: Devices/Smoke Grenade
Cast: 1.37 sec
Recharge: 15 sec
Endurance: 7.8
Range: 80ft
Max Targets: 10

Perception -0.9 for 60s (auto-hit)
ToHit -4.9% for 60s (Not Auto-hit )

Power: Night Widow Training/Smoke Grenade
Cast: 1.37 sec
Recharge: 15
Endurance: 7.8
Range: 110
Max Targets:16

Perception -0.9 for 60s
ToHit -3.75% for 60s (unresistable)

There are clearly some similarities between the powers, however i'm not certain if the Night Widow mirrors the Devices/Smoke grenade in only having the perception debuff autohit or if it follows the Fire Control/Smoke method of applying both Debuffs as auto-hit in PvE. Yep. There's a lot of searching and reposting involved to get to the bottom of this. Can any one help test the above information for accuracy?
