Light armor smithing branch, you can perk Deadra weapons and use the light Dragon armor
You don't even need need daedric weapons or light dragon armor to be by far more powerful than anything in the game, some people like style and some don't feel the need to waste perk points when you can hit armor cap with any kind of armor.
Breton is also the best race.
25% passive given
+25% passive lord guardian stone
+30% passive alteration perks
This is opinion, you don't even have to get hit at all.
80% passive all magic elements without any enchants that you should put towards recovery
Recovery is a waste for illusionists who can just break combat.
+100 carry from pick pocket
I personally have never come close to being overburdened in this game because of good inventory management habits
one handed with a suped up weapon with enchants and healing yourself while recovering stamina at the same time is the ideal perfect build
For you, not everyone plays like you, or wants to.
Some of the stuff you say is true, most of the stuff you mention is personal opinion but you state as facts.
You are powergaming, which is fine for pvp-oriented or competitive games, but it is pointless in a single-player role playing game, unless you like that sort of thing.
I play on master in a completely different way than you and haven't had a single problem. I even completely ignored enchanting, alchemy, and smithing.
There is no such thing as an ideal perfect build.
