The idea is pretty cool and adds a lot of play style choices. Impacts as I see it;

• QQ from other classes as our hots snipes more heals than ever lol
• Building up sets of gear based on your healing assign and encounter (more so than we do now). If we are expecting massive spike damage and rolling multiple sets of hots on more than one boss we may look to drop haste to make the hot tick longer.

It will be interesting to see if and how it is implemented but it could be cool
