Totemic Rsham's "Rain Dance" PvP Talent

Rain Dance currently makes healing rain instant, 30% more effective, and cost 45% less mana.

I’ve no idea if this translates to Surging Totem or is bugged or anything. But I want to use Totemic in PvP. Since Surging Totem is instant already, I think this talent should be changed.

Please make Rain Dance into like Totemic Icon. Puts the totem on an ally’s back. So now healing rain/totemic will be attached to an ally rather than on the ground. That is all, thanks.
