In a lot of MMOs, summons are not viable against other players. They die quickly and/or don't do enough damage.

I'm really hoping this isn't the case in ESO as I love to make conjuration based characters.

How do you think it will pan out in this game?

I agree completely .. I love summoning dremora (preferably 2 at a time) I know in perfect world international the summoned pets were DEADLY! kill most players and the summoner was not weak either. I don't like it to be too overpowering but the ability to GET to be able to summon things to help you should (IMO) be very VERY hard to obtain. making it near imposible to get the higher powerd summons. like maybe only obtainable at lvl 50++.

id also like to add that if you do get this power to summon then your summoned pet should NOT have a timer .. they should be perminant until their killed. I hate having to summon something for 30 seconds or 5 minutes is kind of rediculas.

One of the classes i have been playing around with in Skyrim is the Witchhunter class which uses summon atronachs to distract opponents so they can be attacked by the witch hunter's bow more easily. It would be awesome if that was a viable strategy in PVP and PVE.
