i would say deena
Jericho used to be most important. Almost obsolete now I think unless you have the right tech, but that tech is not available as far as I know. I could be wrong about tech.Deena was the bomb. Not so much anymore, but still useful in some situations. Ardra was key compliment to Jugg, but now everybody runs Jugg with Caretaker, and Ardra has no role of particular usefulness I know of.Roland adds some punch where you need Hammers.Sunder if the most relevant and useful now.Weaver could help out a bit here and there. As could Max probably, but none of the other heros have a major impact as far as I can tell.
