Sham's healing was clearly deficient prev.wipe before legend, this wipe it's sufficient in the most cases. If we do want to make elite shamans heal even better it should be done through some spirit manipulation (so, 'healing done/healing factor' buffs from bound spirits should be increased and visible in affects) or elite eq (btw, I find very annoying that it's impossible to find sensible equivalent to macabre set in terms of healing done). Usual Clerics are better than non-legend Shams, but lose to Legend Shams and Legend Clerics are buff again, looks fine.
Spirits damage should stay where it is now, finding right spirits takes time and they don't live that long.
About transmogrify awkwardness, I already submitted the idea about bind skill at (superb) should not require the spirit to be controlled, it will reduce micromanagement such as when to bind fresh spirit you need to get rid of an existing controlled spirit, control, bind and then have one spirit less, also it's more inline with absorb/channel and also blends well with transmogrify. Also transmogrify will look pretty good as a skill instead of the spell, gaining more features while progressing (merging more spirits/giving better mob skills/creating tougher charmies/etc) and offering good space for exploration. I suppose this skill should be the legend requirement instead of taunt.
Another thing I'd like to see fixed is absorbed skills lifetime. AT LEAST absorb skill cool-down should be removed, none of the acquired skills are game changing comparing to druid/cleric legend abilities and most of them have their own cool downs.
I think I'd submitted the same idea about nap a month ago.
As for other spells, I think it's logical to have DETECT_ASTRAL effect on 'spectral sight' to brew it for your groupmates, maybe 'protection from undead' should become aura at 30lv (or we may need a sepate spell), and I'd like to see 'darkened soul' duration extended and the spell to be brewable, otherwise it's very underwhelming despite the high circle and being required for legend. 'ethereal path' is plain useless now as it was from the very introduction of the shaman class. It should have effects similar to march skill whether you're flying or not. Something should be done about 'evil eye', it never lands in practice. And finally 'last chance' could be made aura (or maybe new aura spell introduced?) and/or its duration increased, cool down reduced, in its current form it's barely used.
