I think he might be referring to the Wrath of Nature spell - encounter dot with a HUGE range, can be cast while moving. It can't be cast on mob if another druid has cast their though, which is a bit of a pain.
The ring of rage effect can't be cancelled early and it's also broken. It's supposed to increase cast time and half healing amount of all heals and wards, which it does, but it also increases cast time (actually triples cast time) of other things such as Fae Flames and Sunrise
