You "balance" for the swell in the bell curve. You let the outliers, the truly [censored] characters or the truly power gamed to do as they will. If a player is utterly unwilling to bother to understand the simple mechanics or spend their perks, or use guardian stones, then, yes their play will suffer.
You write what on the surface appears to be a reasonable post, if the discussion was about some obscure exploit. The fact that Weapons get enormous damage bonuses from using blacksmithing and enchanting AS INTENDED, while Destruction does not is not a corner case. It's the standard case.
What we have here is a case of standard play vastly favouring one type of common play over another.
I have to disagree with a lot of the 'magick is useless/nerfed' argument.
Firstly, a fighter type has to rely on a range of things to survive and win: weapon skills, armour, armour skills, shield (maybe), blocking, etc.
A fighter wouldn't waltz into a combat wearing peasant clothes and only carrying one sword...wouldn't last long at all.
Which is exactly the same argument and reason as to why a mage type has to rely on things other than just 'spelling down' opponents...you can't rely on one thing alone to do it.
You have to cast protective spells, or distractions, or conjure up things to fight for you.
You do not need the armor skill, you do not need the shield skill, you don't even need the weapon skill. All the scaling comes from the Weapons and Armors themselves. Is this really such a difficult concept to grasp?
Let's type that in extra large letters for everyone.
Warriors do not need to spend a single perk point in -any- warrior related skill to outscale destruction. Their scaling comes from the badly balanced weapons and armors themselves.I was just trying to put a Two Handed only Warrior in the same vacuum as your Destruction only Mage.
You can summon pets, calm, fear and paralyze so you can deal damage but you refuse to in this vacuum. So I'm choosing not to defend myself appropriately (like you) in order to use my intended form of damage.
You'd actually win if we went into that vacuum.
There's nothing, exactly nothing, about Destruction that favours using other Spell Schools more then any of the other damage dealing skills.
