Please try to follow my logic, i dont know just the right order to state this in so I will just dump all of it out like this:

The PHB says that Arcane spell failure is caused by armor interfering with your movement thus your spells somatic components.

Armor says How much of a dexterity bonus you can use in it (your range of movment).

You do not need a dexterity bonus to cast spells. You can still cast spells unarmored with a Dex of 3 (-4 mod) so you should still be able to cast spells in armor because no armors take you into negitive dexterity.

I meen realy balence aisde this makes sence, does armor give off a localized, low powered anti-magic feild or somthing? I dont have my PHB with me but I think leather armor allows a +6 bonus to dex and gives a 5% chance of failure, so does that mean that unless you have a Dex modifier of +8 you cant cast Arcane spells without risk of it failing because the pattern of failure increase goes in a pattern with the max dex bonus.

I understand where your logic is coming from, however I think this is more of a balance issue than a logical issue, at least it was moreso in 3.0 rather than 3.5 because arcane spells were undoubtedly, considerably more powerful then divine spells.

A couple of examples:

Time Stop --> back in 3.0, you could cast offensive spells during TS so when it ends, the enemy is blasted with massive loads of damage

Haste --> extra casting action every round, put simply: doubles effectiveness of any caster

Just my opinion.

Armor has an associated Arcane Spell Failure chance (ASF). This percentile roll represents the chance that your armor just happened to get in the way during a critical point during casting. Heavier armors (with higher ASF) have a better chance of disrupting the spell. It should also be noted that spells without somatic components (the "S" in the spells component line) are not subject to ASF from armor worn.

I'm not sure what is unjustified about ASF even if game balance is the only reason for it.

Well, it's kinda hard to follow logic when magic defies it.

Some argues from a different standpoint, the relations between ASF and ACP (armor check penalty toward physical, Dex-based skill). To which I counter-argue that not all spell, especially without somatic component can easily be cast automatically, and therefore it is up to the intended target to evade the spell's effect via saving throw.

That's why wizards opt not to wear armor. It's easy to cast without having to make some kind of roll in order for the spell to take effect. Sure, there are certain spells that require touch attack rolls. But the more powerful spells, once the spellcaster is granted access to it, simply declare their target.
