I have put all my points into Magicka so I would have enough for the upper level spells which require a very large pool to be useful at all. What I wear has no armor so I can easily be one shot by many enemies in the game. My feeling is that this inherent weakness should be balanced out with an abundance of power. Instead I have to fire off twin pop guns to stun my enemy into submission while killing them...very slowly. Multiple enemies can easily become a lesson in frustration. With no good way to stun them all (other than chain lightning which will also kill my allies), and very limited power at my disposal, I'm forced into retreat, or dependence on a conjured ally. My companion is as weak as a fluff of cotton and drops to one knee after a single blow by most enemies even though she is in full Legendary Daedric armor and equipped with a high level weapon. She is a useless tank which is something for another thread but needed to be mentioned here.
I love being a caster, and I appreciate a challenge, but I do feel that the magic in this game needs an overhaul. I don't want to one shot everything but I do feel the upper level spells should be more than what they are. I hope one day to have a better PC where I'm sure magic will be modded to be more effective but for now I'm on the 360 and Bethesda is my only hope. So Bethesda if you happen to read this I hope there are changes on the way. The end game magic in this game is pathetically weak and really needs some tlc. The best way I can see to remedy this issue is to provide enchants and gear that increase magical damage just like the items melee and ranged users have to increase their damage. Skyrim's casters have not been treated fairly in this regard and it is time to correct that problem. If that cannot be done then please rebalance the damage output of the currently available spells in the game so that they are properly effective. Thank you.
