Every mag class can heal everything including vet trials and for dungeons it doesn't really matter. It is just easier for some classes or they have more support utilities to help your grp.
That said, it is a fact that warden and templer are designed to be healers and have better support abilities than sorcs(even after the extrem nerf to shards and repend). I think the basic design of a sorc was as pure dps class therefore they lack support skills. The 2 things sorcs for healing is the twillight pet(can die and is sometimes unwelcome due to mechanics) and the reduced ulti cost.
Sorcs are in this patch doomed to spam heavy attacks as dd, which is extremely boring in my opinion, but still doing good dps.
Mag Warden are in a bad spot single dps wise, aoe dps is actually quite nice. Also half of the warden skills are bugged and extrem slow in animation.
What class is more fun to dps with is hard to say. Just try them both on pts with a max lvl char and decide after that.

Sometimes...I worry I am promoting my own demise as I write these posts. The deadric skill line branches into healing. You could even use dark magic and storm calling for support.
* Easiest access to minor intellect for allies sorrecer have empowered ward
* Root ablitily suitable for Healer who are in the back
* Passive for ult and Magicka reduction
*Passive to excute using shock damage ( best user of elemental blockade as healer)
* Only class to give ally major beseark
*Ability to stun mobs o
*Ability to slow mobs
* Ability to imbolize a mob
* Ability to negate magic
It seems i have different points of view what a healer should do(mine is mostly trails).it is a nice buff but sorc dds also like to use it and it only give the buff as longs as you have the shield(max 10 sec, but realistically ~2 sec)* Easiest access to minor intellect for allies sorrecer have empowered wardnot really the job of the healer(tanks usually do that if needed) and not sure if needed at all* Root ablitily suitable for Healer who are in the back
*Ability to stun mobs o
*Ability to slow mobs
* Ability to imbolize a mob
* Ability to negate magicactually never thought about that but i doubt that it really adds alot of dps*Passive to excute using shock damage ( best user of elemental blockade as healer)It only works if you use the atro as ulti instead of war horn. War horn give a buff to all grp members and atro only give it to one grp member after using a synergy(all synergies are alittle buggy in this game and hard to get)* Only class to give ally major besearkYep that is a good passive for a healer, but all other classes have something similar* Passive for ult and Magicka reduction
