Interface for a Plant/Thorns Dominator.

I'm working my way towards acquiring all Incarnate powers for my Plant/Thorns dominator but have been struggling to decide on what slot from Interface would suit her best.

The problem being that either one could work, and that no option stands out more than the rest. There probably isn't a right or wrong answer, as it is down to what suits me more and that I could (in the long run) just get all four and switch between them whenever I feel like.

Reactive I feel would benefit me in the sense that the -Res would stack well with my -Res procs already slotted into some of my Thorns move, thus increasing my overall damage output. However I'm not terribly interested in the Fire Damage and I feel that the -Defence and -Damage from Paralytic would help out with the innate defence debuff from my Thorns just as strongly as Reactive strengthening my overall -Res output.
On the other hand, I could stack up on -Recharge and Slow Movement from Gravitic and Thorntrops/Carrion Creepers, aswell as it's Recovery and/or Secondary effect Debuff thus improving my survivability. But I could also increase my survivability with the -Tohit and possibly kill enemies faster with the -Regen from Diamagnetic. But would the -Tohit negate my Confuse powers to a small extent?

I understand that the Interface slots are well balanced which is why I find it pretty tough to choose one over the other. Anyone got any suggestions as to what I should choose?

I tend to play damage dealers; blasters, scrappers, and even my main controllers, Fire/Rad and Ill/storm, are damage dealers, so I choose Reactive and work to the 75% chance of fire DOT.

Otherwise, yeah, it's all good. Reactive is unique.

I, personally, if teamed with you, would prefer you had the -tohit.
