You know those people who say there's no such thing as a stupid question? They're wrong.
With the addition of selfless healer its looks like blizz want us to be able to help out with healing if the sh*t hits the fan. I'm trying to figure out if obtaining a 1.6 speed healer mace and shield will be better for throwing out those few WOG heals while the druid healer battle rezzes a dead healer.
Seeing as a weapon like Maldo's Sword Cane would give a lot more spell power than having your normal 2h weapon equipped. Also, having the 1.6 speed would mean more HoL procs.
So far the only disadvantages I can see are that any attack that uses weapon dps to calculate damage will be lower. So CS, DS, TV, Seal of Truth 5 stack and Seal of Command talent.
The benifits of using the 1.6 speed healer weapon seem to be quite good though. More frequent HoL and AoW procs, harder hitting Exo, HoW, HW and Judgements.
Not 100% certain if two handed weapon specialization's 20% damage increase affects all damage or just autoattacks.
