I'm in the same boat as you. I have chosen a Sorcerer (high elf) and I was actually leveling with the class line of Storm Calling. I switched my gear to Medium Armor (5 pieces) and Light Armor (2 pieces) when I realized I wanted to use a bow with a lot of stamina. My attributes are: 20/10/20, so basically I am a hybrid spec between magicka and stamina. I find this very useful because I do not seem to run out of any resource, either from magicka or stamina. This may be something you are interested in.
*I am not sure of all the skill names off the top of my head so bare with me*
The skills I use are:
-Magelight (from the Mage Guild skill line) morphed into the skill that gives me 17% more critical. You may want to look into this because it really does help with my burst. This is up all the time- once you have it on, you do not need to worry about it.
-Arrow Barrage (from bow skill line) morphed into the skill that gives a bigger radius (not the flame spec). This is great for AoE damage, which I find is pretty vital in ESO.
-Silver Bolts (from fighter's guild skill line) morphed into the skill that hits several enemies. This also knocks down undead and daedric enemies! I love this because it really helps for my survivability.
-Daedric Curse (from daedric summoning skill line) morphed into the skill that has less time it is on the enemies and when it explodes it hits other enemies (it starts with a V). This is also another AoE, and works nicely with my other skills.
-My ultimate is Werewolf Transformation which I just use for fun. I will most likely be changing my ultimate to Dawnbreaker in the Fighter's guild.
As for my 5th skill I am not so sure. I have been having troubles with survivability, not having a cooldown and as a level 1 vet I foresee this being a problem.
I will either use Circle of Protection, Evasion (from medium armor)- which allows me a 15% chance of dodging I believe, or adding more AoE/Stun to my build with Trap Beast (in fighter's guild skill line).
At the moment, I am a very bursty class with a lot of AoE abilities and it is extremely fun.
I am looking for any change my build in any way, and I am up for suggestions.
I am a VR level, and I am noticing I need more of something. I feel my survivability will be completely gone once I go to my first VR map. Which is why I am trying to figure out what I could do to make my Mage/Archer better right now.
I am most likely going to be experimenting with cooldowns or AoE stuns. Hopefully this will give me the necessary skills I need to quest on VR maps.
