I don't know about changing walk/run/sprint speeds or anything like that (it seems fine to me), but I would love to see a new perk created somewhere that would allow side jumps.

Idea: instead of choosing to increase magicka/health/stamina every level, make that auto level based on which skills were raised, and instead create new magicka/vitality/stamina perk trees that have perks like...

In Magicka - level 10 requirement - carrying fewer items + having higher stamina = easier concentration, and you get faster magicka regeneration
In Vitality - level 40 requirement - Halo style health regeneration (you move away from enemies far enough, you heal back quickly and you can go back to fighting. Probably imbalanced, but hey it's just an idea)
etc

Having Magicka Regen scale with total magicka.
Reducing the number of gear slots that can be enchanted with cost reduction. 25% is fine, 100% is stupid. Or, cap it at 50% or something.

I think pretty much everything also regarding making magicka less [censored] has been mentioned.

Oh, and nerf Daedric Lords or something. Or make the twin souls perk make your second summon cost double Magicka, and then not be able to regenerate it when they're out. Two Daedric Lords is just....[censored].

I'm almost sure it already does this. i.e. regen is percentage based as it is. I could be wrong, though .

I just have a few ideas to somewhat balance the game

For crafting I would make it so that the crafters dont sell nearly all the ingredients you need to make stuff right there at the forges

Next I would make the high level ingredients more rare and have them only start appearing in the game at the level which is appropriate

The potions or the items to buff crafting would be made a lot rarer and the buffs on the items would be reduced

No 100% items dropping in the game. I got a 100% disease resist necklace

At low levels 50% resist stuff would be rarer. The max would be something like 20-30% or so

Any drastic changes to the crafting system would be too difficult I think to do.

To me its too easy to break the game with crafting. You cant stop people from doing this but you can make to so that it isnt handed to them on a platter.

My philosophy is that if you try to play normally without min maxing through exploits you should be able to.
