Now, this situation occurred to me whilst rolling a Mage archtype. Focusing on Destruction/Restoration/Conjuration. I am level 5 and currently cannot use Conjuration. Boldly, I assaulted this Giant with flames on each hand, since holding a healing spell in one hand is futile since any damaging strike will outright launch you into orbit. Using the environment, observation of his movement and attack patterns, I actually managed to kill him, without taking damage.
Sure the battle might took a minute or two and a lot of running and using elevation, but I managed to do this on a level and fashion I held impossible. So to all you Mages out there. Use your wits, common sense and your arsenal beyond Destruction to survive. Currently summoning a Fire Atronach as my 'defence' helps me out in a lot of situations.
Take this as an encouraging thread and find comfort that this is a viable choice. I know I am not level 40 and have yet to suffer for the non-scaling of my Destruction spells but there are always ways to compensate for this, I am sure of it!
