Skyrim Illusion/Alchemy/Pickpocketing

I've recently made a new character in the game Skyrim, which focuses on skills which aren't directly combat skills (like illusion). So I'm an high-elf which is about at level 20. I use the illusion to calm enimies or make them attack each other, and I use the pickpocket/alchemy to put poison in others pockets to poison them. My high-elf character hasen't focused much on the main quest, but went to the Collage of Winterhold. So, he's more focused on the wizard part, more that the thief part. However, now I'm not sure if I should join the thiefs guild, get armor instead of robes and lean more over to the thief part.
I'd like to get your opinions, since I need some guidance towards what to decide.
Also, I'm sneaking a lot.
Thanks

 

Keep in mind, no direct combat skills

 

Learn how to summon animals to fight for you.

 

True true, that could be done

 

How do you defend yourself from Dragons if your character has no combat skills?

 

He kind of doesen't...
What I've done till now is mostly running away from them and hiding.
However, kinda don't play the Dragonborn part of Skyrim, so I'm trying to act as much as I can as a thief, not a Dragonborn.

 

The best thing to do is to FUS RO! Oh wait, we're already dead.

 

Haha, lol.
That could actually happend to my character...
He has like 120 health and 400 magic

 

have you gotten the skeleton key and the invisibility spell from the Thievs Guild questline?

I play LOTS of skyrim

 

And have you joined the Dark Brotherhood yet?

 

Why not do both? Have em be a master thief who has decided to try and better himself by attending college.

 

Yes, I've finished the Thieves guild and got the invisibility spell.

I didn't plan on doing that, since my character isn't an assasin, but more of an pacifist.

 

hmm,
