New player : advices welcomed on paladin support build

Hi all, I’m a new player here (level 16 just to test). And I will play soon with 2 friends at release.
I want to play a very oriented support offensive/defensive class.
I’ve selected (cf. Link below) these skills (and skill trees) to achieve that (don’t look to passives yet).
Do you have any insights which could enhance this type of build please ? Even if I know a lot could be changed at release. Thank you very much.
