Simple armor rebalance(SAR) - it's a lightweight perk overhaul for armor and blocking, it don't use any scripts. 
Perk trees is very similar to vanilla. I reduce a defence bonus(heavy armor give 20% less defence, light armor 40% less ).

Main features/changes/new perks
Heavy armor:
New perks:
 Cavalryman - You take 30% less damage when riding horse (this perk is instead of Cushioned)
 Well protected - 50% to poison resist 
Changes:
Juggernaut now has 3 levels - 25/50/75%
Reflect blow give 15% chance instead 10%
Wellfit and heavy matching set require 3 parts of armor.

Light armor
New perk:
Hit and run - all weapons(including unarmed ) do 15% more damage.
Changes:
Agile defence now has 3 levels 20/40/60%
Deff movement now has 3 levels 10/20/35% and work only when you move or sprint

All light armor perks which require full set now require 3 parts of LA (I did this for possibility to wear heavy gauntlets with light armor set, I also increase  unarmed bonus damage of all gauntlets (just a few percent, it shouldn't be overpowered, for example daedric gauntlets base damage is 25 instead of 18) 

Perks deff movement, windwalker and hit and run will work with clothing/unarmored too.

Block
New perks:
Firebash - bash by torch do double damage (stack with deadly bash) 
Changes:
Shield Wall has 3 levels 15/30/45% 
Deadly bash has 2 levels 5x/10x damage 
Shield charge - now  knock down has 25% chance instead of 100%
