Remember that the spellblade passive on IBG deals 125% of BASE AD in an aoe in addition to a slow. Its meant as an item for tanks and bruisers to get if they need more damage and stickiness. Since it scales off of base AD champions with high natural ad like Cho'gath, Skarner, Alistar, Blitzcrank, Malphite, Maokai, Nasus, and Hecarim have better synergy with this item than say Thresh or Orianna. It also gives a nice chunk of mana, cdr, and armor to boot, which all of the champs I listed above love to get. Additionally, since it scales with base AD it also means that the only stat that the spellblade passive scales with is level. IBG only gives AP due to the build path of sheen. Its not meant to scale with either bonus AD or AP, which is why it is usually the only item that increases damage output in most of the builds that it is included in. IBG is fine where it is imo, it gives a plethora of useful stats for a good price and is neither OP or UP.
