I think there needs to be a lot of choices when morphing spells. 2 options on morph is decent but defiantly not enough. You should keep all play styles in mind when making them. Also there needs to be Morphs of Morphs that keep going as you progress. One set was really not enough.
example
Sorcerers would make great spellswords with a 2h if it weren't for the 2 second cast time on that shard stun. If you could morph it to be instant cast, that would fix the problem and open the play for other styles, even if you had to reduce the damage on the morphed version. Without it being instant cast it makes melee sorcerer clunky.
IMO there needs to be a couple more classes/changes.
Dragon Kight, Templar, and Nightblade all seem decent.
Sorcerers are okay but they don't fulfill what I was expecting from a caster class. I would change the Sorcerer into more of a witch hunter/witcher. Not many if any changes would need to be done.There needs to be a Mage class that is solid fire, ice and lightning, with respective atronachs for ultimates. There needs to be a Necromancer heavily based around dark magic and conjuration.
There also needs to be a "warrior class" which you'd probably have to base around earth and lightning attacks(slaming the ground, calling lightning, causing fissures and earthquakes, etc.) I know anyone can pick up a sword and charge in but it would feel better if the magic looked like "strength magic" as opposed to another magic skill tree's. Nightblades come close but still feel lacking.
All in all. This game looks great and has a lot of potential but the classes need a lot of TLC.
