Okay,you don't agree with the "rune master" logic that's fine. But what about the having "Master Destruction" as the final perk? Do you agree that is kinda lame and that something is obviously missing?
Considering Alteration's final perk is "Atronach"-Absorb 30% of the magicka of any spells that hit you.
OR
Conjuration's final perk is "Twin Souls"-You can have two atronachs or reanimated zombies
DO you get that logic,or are you too slow?
Chill out mate, what was that about? I'm allowed to disagree with you, don't take it so personally! Why resort to insults rather than debating a point properly?
The thing with Alternation and Restoration are they represent in some respect, collectively, genuine alternatives to wearing armour. They need to have that kind of major perk at the top of the tree
Think about destruction though - a ranged attack that could recharge quickly, but (for example) had a 15% of killing someone (like a bow does) would be too overpowered. Imaigine using the flame thrower spell that had that? It would absolutely destroy people.
The other thing to note is that there are several high powered perks e.g. increased damage for fire, frost and shock. You could already have boosted spells by the time you reach master, and having reached 100, all of a sudden you get access to new Master level spells that were previously unavailable - which I can only assume are pretty devastating.
So having reached 100, your mega-master level spells only cost 50% of the base cost, and are 50% more powerful - that sounds pretty good to me.
I agree that there's no specific "you've reached the max on destruction, have the keys to a mega bonus" type perk, but generally it seems to be a very, very powerful skill to have, absent any further bonuses. Just my opinion.
Note the lack of insult at the end of my post
