primarily a pally here, just browsing for some low lvl ranger info and I feel I should comment. My single taunt, shield bash, and AE taunt were all adept I at the time this event occured and amends was adept III (41%). I was 54 (or 55 dun remember) and invited a ranger the same lvl as me to help the group hunt harpies. I was confident in amends, told the Ranger to take off all "aggro control" items she had on and go all out. She told me she had mostly adept IIIs and a few adept Is, but we did it anyways. That mob died faster than anything I've seen before and I only taunted once.....never lost aggro. It's so much easier to hold aggro with a ranger in the group even. Just let the tank get a taunt or 2, give him just a couple of seconds, and nuke away. If the paladin knows wat he's doin, he SHOULDN"T lose aggro, and if he does we have some excellant recovery techniques, so dont worry about it (rescue and Sigil of Heroism for the most part, plus intercede/wards/heals can help save some ppl).
so in answer to your questoin, get rid of all your debuff/transfer things and just use amends, youl'll be fine.
