missed opportunityFollow

I have a 63 healadin with full healing gear. I was hanging out in Hellfire trying to get my mining up and very slowly soloing some quests when I receive a whisper asking me to tank Ramparts. I usually run with my brother and his wife and I play healer we have 3 manned up to the 2nd boss in Blood furnace so I know instances but I have never attempted to tank anything.

Here is my armory http://www.wowarmory.com/character-sheet.xml?r=Baelgun&n=Aldelona, do you think I missed an opportunity by not trying this or do healadins make lousy tanks?

The problem I see is mostly agro generation and damage mitigation....

I've been working on tanking and agro seems to be biggest issue as a new paly. I can't see your build, but I guess you don't have Improved agro generation... When you get a few pieces of +Spell Damage you'll likely have all the agro you need IF you have the Improved Righteous Fury...

Also - you will require a lot of CC. As you are not spec'd to take 3+ mobs pounding on you, you can't do what many paly's do - which is multi mob tank. I'm not sure if it's correct, but if we lack CC (Say we have 1 mage and nothing else with good CC) I ask the mage to sheep - while standing next to me. I drop Consecration and ask the mage to Nova them when they get into my AOE range. Then let them hit me and I build agro. You can't do that. You can tank 2 or 3, but not much more. As you take more damage than a Tankadin, you're healer will heal more - You generate less Agro than a Tankadin - the healer might pull agro... You don't have the abilty to generate a ton of agro quickly...
