I'm level 60 and specced all the way up to Beacon of Light in the Holy tree and plan to go some into Ret next. Anyway, I healed my first couple of Ramps groups and they went "okay" but not as smooth as I like. Now part of my problem here is the people I was running with are a bunch of new and thus novice DK's. Ideally I'd like to run with a group of skilled players to see how good or bad it goes so I can get an idea of how my healing is. I have a few questions though cause I'm a little confused.

1) With 2 Major & 2 Minor Glyph slots, what do I use to fill them? I'm using the Flash Heal one that makes it partially a HoT, I can't say I like that too much but I'm not sure yet. I'm also using the Seal of Wisdom glyph to make healing spells cost 5% less. I was considering switching over to the glyph for Holy Light to heal people around, and the glyph that increases your healing by 5% when the light seal is up.

2) Does every one of my healing spells work with Beacon of Light? There were a few times where I BoL the main tank, another member or myself got hurt and I would cure them and the tanks life didn't go up. I read a tip to put the Hand of Sacrifice on the tank along with Beacon of Light, then just heal yourself essentially reducing the damage the tank takes while its up. I tried that and I would Holy Light myself and get the heal but the tank wasn't. I'm certain the Beacon was cast on the tank and not myself. Is there a distance factor? I was only probably 20 yards away and had the BoL buff.

It was a very sloppy group like I said, so I guess its a good thing that an at best average geared Holy paladin was able to keep them up. Any help with the glyphs would be appreciated though. I am a little unsure what to do there.
