unfortunately that just wouldn't work...mages aren't meant to be templar prophets...in any game,can name a few games that tried it and those classes are extinct in those games..mages are the fan favorite styled class that people like to deal damage in unique ways. resurrecting dead to fight along side,summoning a bunch of things to fight with you (that are worth having) or high very slow dmg.
Also the class you are seeking to be made already exists,its a prophank. IMO its a bit over powered...making a class further that process would just throw the entire game off...wouldn't even need other classes. so by making a class such as this they would have to completely defeat the ability for a prophet tank hybrid or else the mage(prophank) would be useless and not played.
Mage needs new mechanics that are unique,and i pointed this out above...mages don't need slows and stuns on all their moves...they need uniqueness to damage. keep despair how it is...add something to blizzard and overload hell even remove one or both if you have to to make something different. but to diffuse an entire tree..just to make something replicate something already existent I don't feel is the way to go.
The scenario you stated above is already able to be done by current prophanks also.

Meleager you need to play mage to understand how weak it actually is.
If you want to whine about cauterize take in notice rangers(warriors/sins) can kyte equip essence cauterize and heal 72% with same power(both using fabled essence, only 100 fabled relics) as a mage and equip bow and continue doing stuff, with higher dps and armor.
alas my point is if mages have less armor they should undoubtly have the best aoe dps of the group but mage skills are nerfed to the point that i see no mage around except dasan and ben.
And its worse then the other classes, and one of them says everyday i only play mage cause it aint so easy to win and gives me the thrill to do it.
and they are always doing pvp cause its the thing mages can do somewhat not that bad
even john respeced to hybrid to have a better dps.
as said before mage needs a stronger blizzard and a fixed/improved chilling
i would like to see the mage with 2/3/4 summons that would make mage a summoner and give him a different purpose from the other classes. maybe void portal having 3 possible upgrades one per summon or anything of sort, and still be able to aoe decently.
