Well, I found a new strategy to heal through Loken. Others probably already know it, but I thought I'd share it.
Usually, everyone runs from the Lightning Nova. Well, as a Holy Paladin, the group doesn't need to. Just engage Loken, and power heal through it.
1) Put Bacon on the tank.
2) Everyone engages, and stays close to him to reduce damage from his Pulsing Shockwave.
3) Make sure to keep everyone topped off.
4) When he starts casting Lightning Nova, get everyone topped, and start to cast Holy Light on yourself (making sure it casts AFTER the Lightning Nova).
5) Lightning Nova will hit everyone for like 10k or so. You'll quickly have yourself topped off, and the tank (with Bacon)
6) Then, cast Holy Light on the 3 DPSers. That will top them off and keep the tank at full health.
7) Then, keep everyone topped off.
8) Rinse and repeat.
This way, the DPS never stops, and Loken dies fast. It works wonders, and is really easy. Much easier than running from the Lightning Nova.
Enjoy
