Indeed Alaris, which is why I think it would be good in pve. The issue I see with it in pvp is that sins can already take people down easily. Throw in the ability to have three skills do three separate things depending on the order you use them in, and that's a lot of bar compression. You're basically getting 9 skills in 3 slots.
Think about it this way, if elementalists got a skill that would do something different depending on how close the enemy was to them (blind if adjacent, daze if they're in the area, or cripple/knock-down if in earshot) would people not complain about that skill?
At the same time, skills that do one thing or another depending on the circumstances are not new and I could see that happening with dagger attacks even in pvp. It would also open up a lot of combinations depending on how many skills were made that way. Which, I would imagine if they did it would sort of end up like flash enchants, in other words, fairly common.
