Hehe, I suppose the easier thing to say is, its better with friends More water blast is more fun ^^, I'd recommend looking at auramancers stuff also, I've got mine setup with Ascended Celestial Gear and have had a fair bit of fun with Aura's despite it not being an optimal PvE build (The one I'm using at least xD), some parties will also have quite a bit of fun with the aura's themselves doing things like running straight up the deadly stairs in the Uncategorized Fractal for example (Magnetic Aura reflects the lighting strips straight back up and is good for the harpies ^^).
Good thing is you enjoy it mostly! Once had fun when we had a Clerics Warrior and Clerics Ele some time ago spamming Ice_Bow's at Mai Trin in a pre HoT Expansion level 50, face tanking was great (1k heal from the Ice bow on the Warrior adn Ele helped me thinks :P)
