Thanks for the advice! The only real problem with the standard Restoration spell is that it
takes pretty long to heal yourself, especially when you only have one hand.
Where can I get "crowd control" spells? Also, you said "If you plan on getting in melee range at all..."
Can I really stay out of melee range?
I just fought a Bandit enemy with strong armor and a Greatsword, and I had to use all my
healing potions to survive
I used my shield, mace, and heavy armor, all of which have a couple
of perks to support them, but his attacks did a lot of damage. Draining his stamina sounds like a good
idea, but I don't have any frost spells.
And to Woe is Adam: I do use sneak a lot, especially with my bow and arrow. However, why would
Light Armor be better with sneak? Does it make less noise? Does it even make you faster when wearing
it?EDIT: I've invested two perks into Destruction: the first one, and the one that makes Fire spells 25% stronger. First off, you need to settle on your choices, so you can get more focused advice after that. Keep 3 basic things in mind when choosing your skills: Damage, Survival and a "backup".
How do you want to deal damage? Do you like fighting at range, or do you prefer close, melee range combat? This is very important, as your survival skills should be chosen with your damage skills in mind.
How are you going to make sure you kill your enemies before they kill you? You can choose heavy armor or alteration shield spells and take the damage up front. You can choose sneak or illusion (or both) and kill the enemies before they react, without having to fight in melee range and fleeing (or invisibility) if detected. You could use conjuration to create a distraction while you kill the enemies and they are focused on your summons. Or the Impact perk and dual cast destruction, so they never get to you.
And what if all that fails? You should always have a plan B ready. When things get ugly, you could use restoration to heal yourself, or restore health and magicka through alchemy potions, or use invisibility (illusion), etc.
Choose between all that, and you will be able to get more specific advice on your skill choices. If you want to keep archery, ok. But if you're going for heavy armor, sneak is not a good idea (sneak before the opening shot anyway for the damage bonus). Then you will need a way to keep yourself alive in melee. You could use illusion if you want, but invisibility in particular will not be very effective in heavy armor and complements sneaking better. You could use dual cast impact perk destruction spells to keep the enemy at bay, but then you will need either points into magicka or enchanting. If you're choosing magic, increasing magicka or enchanting for a single school seems like a waste, so you could get conjuration too, as it doesn't require a lot of perks. If you prefer your shield and melee combat, honestly a one handed weapon would be better. Or you could go the sneaking route if you like it, but then drop the heavy armor and get illusion (if you're going for magic).
You have a lot of choices. Pick what seems fun to you, what you like playing. Good luck and have fun.
