Sorry, I've not really done much tanking so I gave up on reading most of this thread.

I just wanted to say that new players get very confused by the level 10ish (i don't remember, I did this on alts a year+ ago, it might've even been less than level 10) skill that improves healing effects. They start in Uldah where there are no healers, there's no healing spells in their higher abilities and they probably have not yet run to Grid to unlock CNJ so the skill is useless until they do that or get level 15 to fly there. Even then they may not understand the concepts of cross classing yet. In general, I think introducing that skill so early is a very bad idea which is neither useful (as this stage of the game at least) nor does it make sense to directly try to cause confusion like that. I don't think any other class has a skill that relies so heavily and exclusively on cross classed abilities, let alone so early that you won't have access to them.
