Hmm it's certainly true that the extension at the top of the line adds on some extra skills debuffing. And it has the advantage in ease, of having all 6 nanoskills rolled into the debuff - and the debuff rolled into a nuke of course. So all in all, at higher levels there's a definite win.
At lower levels, there's a definite loss though. Since the Dominates/Unmakes were RK nanos and had low skill requirements, you could access an extra 75 or 125 skill debuff very easily from really quite low levels. And of course, at those lower levels, that amount of debuff was a great deal more debilitating.
In past discussions about making mini shutdowns instead of Dominates, rolling all the skills up into a single debuff, some people also expressed a disappointment about losing the skill needed to choose the right debuff for your target. Rolling the debuff entirely into the nuke is an even greater overall simplification of play. So some people may feel, that there are losses in game-play, though without seeing how all the other changes (esp. cooldowns) play out, it's hard to assess what game-play will actually look like.
Of all the changes in the nano document, this one is one of the least worrisome though. I do worry about how much of the changes that they planned, can now be implemented and so from a lobbying point of view, it would almost certainly be better to focus on higher priority issues
