I think this bonus should be changed to something crit related (-% chance to be crit or - crit damage %) or even toughness, something the shaman is clearly somewhat built around (evidenced by the toughness buff on the hot and the toughness debuffs, 2 if you're dps)
Are possible changes for the -armour penetration set bonus, which is out of place on a cloth armour class.
Ideally, this proc would be as on live, where it could trigger from your hot ticks as well as direct damage (shammy is a hot class after all, and it's not like you have an aoe one for easy procs like dok/zeal) or, it needs it's chance to proc increased (it's not like shammy is a wp/dok with 1 second group heal, or an instant cast direct heal that can hit up to 24 people).
Are suggestions as to how to improve the 7 pc proc. Given that the standard shammy hot would still only have a 41% chance that 1 of it's heal ticks over a 15 second duration would proc this effect, it doesn't seem unreasonable.
These would be far more useful as pretty much anything else, more raw stats or maybe some heal crit or -chance to be crit.
Maybe I wasn't specific enough and had to say exactly what stats I would like these changed to, so:
On the boots, the 2 morale/sec take up 10 stat slots. This could be improved by changing it to any of the following:
1% Heal Crit
-1% chance to be crit
or just any combination of 10 wounds/toughness/ini
On the Belt, the 2% dodge/disrupt takes up 24 stats, so these could be changed to:
-2% chance to be crit +4 stats (wounds/toughness/ini)
maybe put in 1% heal crit instead of one of the -chance to be crit.
On the Helm/Gloves combined, 47 healing power takes up 31 stat slots.
If this 31 points was reallocated into literally any combination of heal crit/- chance to be crit or wounds/toughness/ini it would be an improvement.
The jewel also uses 12 stats for it's -2% armour penetration. Again, any combination of heal crit/- chance to be crit or wounds/toughness/ini would be an improvement
