Here is the stats on Desperate Renewal:
3.0 cast time (1.6 with spell time decrease)
1375 mana cost
4935 hps healed
30 sec recast time
Here is the stats on Ancient: Hallowed Light:
3.8 cast time (2.1 with spell time decrease)
775 mana cost
4980 hps healed
2 sec recast time
Now I know this spell is not used to be an everyday heal, but it has double the mana cost (which is understandable, seeming as how its a quick lifesaver), but with only a half a second difference it's hardly even a save. Plus, it doesn't even heal as much as Hallowed Light. I am not sure what admins plan on doing to this, if anything at all, but I suggest either increasing the hps healed quite a bit, or decrease the casting time a bit so we can make this spell worth the 30 sec recast time and the double mana cost. The one spell I am looking for is a quick lifesaver when a groupmate takes a flurry for 80% of his health and I cannot get to him in time. Typically its just "cross your fingers and hope DI works" type of fighting.
