We build Sunfire Cape cause we wanna deal damage

otherwise there are tons of other defense options that are made for pure defense

These items seems to be Juggernaut Items does magic damage to nearby enemies every second does damage and slows

These items are made for pure defense reduces crit damage and basic attack speed reduces attack speed and gives cdr and mana health and health recovery healing and regen booster gives massive defense but reduces the damage you do to enemies

so what sunfire suppose to do is focus on the damage side of it because its why you build this item - you want to some deal damage and the nerfs kidna don't make sense

If we want to make it weaker early game we should give it health scaling

Sunfire should deal 5 (+1% max health) magic damage to nearby enemies and does 30 bonus true damage to minions and monsters for farming

for 1000 health you deal 15 magic damage /s for 2000 health you deal 25 magic damage/s for 5000 health you deal 55 magic damage /s

that way it will reward when you stack health and not so much when you have no extra health Sunfire cape will synergize with for AD Champions for AP champions
