Small group support viable? ( WvWvW )
Use the PvP build as a base. Your build almost looks like a raid build rather than one to use against humans.

The regen from shouts and staff will do a lot of “top-off” healing and charge CA before the cooldown is up, and if people get in serious trouble stealth them with the smokeskale or celestial shadow.
You can still work warhorn in there, but LB has a lot of good utility on it as well, like the knockback and ancient seeds to help your teammates spike someone very quickly.
Edit: Also pigs are awful.
You could also look at the roaming shout build. With the trooper runes and traited you can apply swiftness,regen and clear condis from allies from each of your shouts which will probably be 3 or 4 skills.
Its quite forgiving and flexible so that you can change the odd trait/skill or weapon choice to your own preference. i tend not to run staff since i dont seem to be able to get the best from it

Both this and the pvp shoutbow fluffball stated are good starting points
