This is indeed a problem. It should be made so, the char walks left and right but the game acts like he's still. I would also like to note that, unlike other heals, while it is being channeled if you open your map it becomes transparent and, while it's usefull in Pvp, in pve it is kinda annoying because you have to wait untill the channel end to look at your map. A very little thing, indeed, but a problem nevertheless.
