Thornmail Changes
The item is designed to more or less prevent AA based champions from sustaining off tanks, but it is counter-intuitive with Frozen Heart and Randuin's Omen.
It was too oppressive as an early pick up on bruisers who did not end up building full tank.
Everyone outsustains the item now, even against full tanks.
Suggestions:
Thornmail +100 Armor UNIQUE: Reflects 20% of the physical damage taken (+ 30% bonus armor) from basic attacks and on-hit effects back to its source as magic damage over 1.5 seconds (Calculated before any resistances or reductions are taken into account). UNIQUE: Healing effects from basic attacks against this user are reduced by 40%.
REASONING: If you have Frozen Heart and Randuin's and an attack speed slow in your kit, buying Thornmail seems VERY counter-intuitive. The live form of Thornmail also is much heavier-handed against high attack speed champions than it is against someone like Jhin or Caitlyn. Therefore, I bumped the reflection damage slightly, but spread it over 1.5 seconds. This should result in less damage overall to most champions, but it won't be as AS dependent. Rather than just making the item apply grievous wounds, I made it so that all on-hit healing is reduced by 50%. This directly punishes all basic attacks against the tank, but leaves alone things like Summoner Heal, ORANGES, Support heals, ETC... I believe this to be a fair way to counter lifesteal without breaking the item.
