Channeling Rit went first.
After trying out a few differing builds and combinations of skills the best I could muster was getting the 3 JB Knights down to about two thirds of their original health. My method was to cast Destruction. Wait 20-30 seconds, cast Destructive was Glaive and aggro them, draw them over to the spirit, and, whilst doing so, cast Spirit Rift. I finished casting Spirit Rift by the time they got to me so I could drop Glaive's Ashes, use Ancestor's Rage and Feast of Souls to destroy Destruction. I then died.
Air Ele was up second.
The best I could manage here was getting the JB Knights down to about half health. I used Air Attunement followed by Aura of Restoration, then as I aggroed them cast Chain Lightning and when they got to me I used Whirlwind. I then cast Invoke Lightning > Tenai's Wind > Lightning Touch > Whirlwind...then I died.
So on the face of it the Air Ele won...sort of. I'd rather have actually managed to get the Jade Brotherhoods down. I decided to cheat afterwards and used the earth magic skill Stoneflesh Aura and with that on I could get them down to about one third health.
So. Some people claim Channeling Ritualists are more powerful than Air Elementalists. I don't see it. Aside from anything, my Ritualist's atempt to get down the Jade Brotherhood Knights also took far longer than the Elementalist's since she had to wait for Destruction to be alive long enough to do any sort of damage.
So onto my question. How powerful can a Channeling Ritualist actually be? Has anyone come up with any builds that are actually worth being used? I only play PvE...so...is there a Channeling build that is of any vague use here...that might have some form of respectable damage output? Earlier I tried using Generous was Tsungrai and Caretaker's Charge. Can someone tell me how that is a good elite? I mean, the energy gain is nice but other than that...the damage is just non existant. So if you're going to spam that you might as well just tickle the enemy.
I'd be interested to see if anyone can get those Jade Brotherhood's down. They are pretty tough as test subjects I guess...
[Edit: Oh yea, while I remember Vengeful was Khanhei isn't allowed, mmmkay? I already know that works...and it aint Channeling
]I don't want a PvP vs PvE debate either...please keep it clean. I don't care who would win in a fight if you battled the two. In my search for Channeling builds GuildWiki seems useless... All I'm wanting is to know if I can get my Rit's PvE channeling capabilities as good as, if not better than my Air Ele. Any thoughts?

It just goes to prove how bad Destruction actually is. Like I already said, Monsters kill the spirit before it can actually be of any vague use...so it's just plain not practical to use it in PvE. You can't really say "Sorry guys, can we wait for my Destruction to charge up for 25 seconds before we aggro them?"...apart from anything the Wammo will take no notice and charge straight on in anyway. By the time Destruction will have "charged" the mob will be dead.
