So people should recommend changes to it in the way we expect it to be changed towards the end of the PTR? I understand where you're coming from, but your argumentation is somewhat strange. These people are giving suggestions to change the spell in it's current form.
And we're talking about Blizzard here. A very small percent of changes are tweaked when they're put onto the PTR, which defeats the purpose, but I wouldn't be shocked if this went through.
Like wise, I just find "Ring of Peace should also effect friendly targets and reduce all damage from within the ring to 0" is not necessary imo, yes it needs to be a 4-5 sec silence/disarm on a 1.5m cd (or 2min), and needs to be able to trinket, spellsteal (maybe) and be tweeked, but if your running a melee cleave or what ever and your trying to get a kill and you use RoP, your team and enemy's team will be just sitting there, and if you try to kite they will just sit on you(guess thats why you'd have a caster on your team). The radius on RoP is pretty big when i played PTR.
