Yeah, definitely! In addition with there being too much passive healing, the actual amount that the totem heals is abysmal, it's not even worth casting in most cases unless you either have the talent, or are Restoration and even when taking those two points into consideration, it's receiving a 50% reduction in healing come Warlords anyway, so there really is no point in having it anymore.
A damage reduction cooldown that you can use on allies? You mean like Ironbark, but in Totem form? Great suggestion, but I don't know how it'd work as a Totem, or with Spirit Link Totem; there'd have to be some sort of compromise. It'd have to be weak, and then Elemental and Enhancement would be given passives that increased its effect, or something or other.
Stone Bulwark Totem becoming baseline, as well as not having the Totem to be active would be really nice. Scratch that, how about a 1-minute cooldown absorb based off of Stone Bulwark Totem but without the Totem?
