How to Improve Sorcerer Healers in Gameplay

Issues with Sorc healers 

• Are lack of heals over time in toolkit outside ultimate
• Be brought for conduct synergy
• Lack of Effective Group Utility 
• Twilight only non ultimate skill heal in toolkit being used skill mostly be dps Sorcs

Underused Skills that Could be Turned into Utility

Lighting Flood - for most part is only used by solo players and some people wanting more room against moving bosses. They could just increase radius of liquid lighting and make Lighting Flood apply a heal over time with it's synergy. Another option give it minor evasion proc for anyone who uses it. Like they avoided lighting strike? 

Crystal Blast - Should be used as instead to crystallize area giving allies a buff in magicka damage or reduction in magicka damage to allies? (The crystal protects them from magicka)

Another option would be to give it crystal weapons to allies. Can even make it cost stamina and give stamina Sorcs option to bring this utility too or tanks. 

Underdeveloped Skills 

Restraining passive - Would be nice if this range skill could be apply something to allies like necro root skills.  

Empoward Ward - It gives minor intellect to allies but unlike warden you can't target the 6 who can get it. Also warden does same thing with healing, and giving stamina regain. Would be nice if they gave it major intellect instead which would make it less useful on dps or simply just more regain. Another option would be really make pet healers if they allow it empoward ward to give buff to group depending which pet you have slotted.
