TONS od Armor? -> in laning phase barely noticible ( you'd think standing in minionwave would hurt less, but it simply doesn't) 40 ap = 6 Armor, whoah... Less than 100 AP means ~10 Armor (that's less than bonus from seals). Mid game - 300AP -> 45 Armor. thats ~800 Gold ( buffed chain vest), 700 ap ( optimistic) -> ~100 armor... not bad. around 1600 gold for this stat... but matches end around 500 ap. -> 75 armor, ~1100 gold... -> not TONS of armor, just good amounts. nice touch, but doesn't fit his offensive kit.
