as a few recommendations to your build:
Drop the level of Seed bomb. The skill damage might be good, but it scales badly and the CD is pretty high to use it frequently, so best is to drop it to level 1 and level the Thorny Vines skill to level 1.
It deals ± the same damage you get from the level difference between 1 and 10 Seed bomb.
If you want to run a support build, I recommend increasing the level of Sterea Troph to 10, and also to learn Shape Shifting (need level 1 only) and Transformation (level 6 required).
The reason why I suggest this is because the transformation into a large insect will drastically boost your own survivability, as the Transformation attributes boost your max HP for being a large monster and your defence for being an insect type.
That way you can concentrate on supporting your team with a problem.
At Paladin, Sanctuary is the skill to go to if you want to support. It adds property damage to the attacks of your allies based on the amount of defence you have with up to 33% uptime.
Once you reach a decent level of equipment, you can help a lot at endgame this way, as the additional damage ignores the defence of enemies.
I’d drop Restoration to level 1 or 4 and grab Smite at least at level 1, it can help a little with its triple damage to mutant and devil type monsters and its knockdown attribute can help to move mobs (e.g. in Velcoffer Nest Stage 4).
