Well , I put hit on gloves instead of SP @ chardev, didn't I ?
If not then there you go
As a defensive healer you won't need more than 15-20 hit( the more the better ofc) but just don't waste other stats to get it.
Also, the leather equivalent for casters is complete shit at this level if you wish to have any Spellpower at all. The cloth also has far better stats and will give you more survivability in the long run with its extra stats than the leather's armor.
If you are going to be playing offensively, I suggest you get a minimum of 25 hit(30 is cap). But realistically you will ALWAYS be the nuke target or switch target due to just how squishy druids can be at 39. Get your positioning right and you can get away with more Sp over stats. Try to tank like other lvl druids and you will hate playing druid.
