Personal experience with Plant/Psi is that it is a super strong pairing. Some of the anims are a bit long on the ST powers. If I was rolling today I'd go /Fire.
Plant does so much work, not sure it really matters much.
Thanks for sharing your builds. In process on mine and will share once I firm up my decisions on a few questions I am debating.
Curious if any other Dark/Dark trollers are feeling like Darkest Night isn't as useful? I haven't taken it yet at 38 and haven't missed it. I feel like we have enough lockdown and -tohit that the cast time isn't worth it. Thoughts?
