Aspire to be something other than a monkey at a typewriter.
I can't understand the number of statements about how little the shields ,like 900 dmg absorbs, are so many. We can see many WWS parses in Ulduar which for example healing stream does %20+ healing with 500ish ticks even it is not raid wide, without an icd the bonus of the mace is very good and i m sure with so many consistent dmgdealing towards the raid , even with the little 900 dmg shield procs plus spamming aoe heals , Val'anyr proly suits its legendary name with the bonus.
And i must add that sure i think the same way about controllable heal is too much preferable than some proccing shield but after some point raid healing is just about a bit of spamming with eyeclosed occasionally (for aoe healing classes mostly) and without icd i m pretty sure there will be too many shields on many raid members just like the healing stream ticks. An item that holds a buff that good is legen...wait for it...dary to me
