Enchantment bloodrazor need some adjustment

Actually this item is the worst compared to the other jungler item even his good stat (4% max hp and 50% attackspeed). The main issue is that his best user prefer to take enchantment warrior for their good ad ratio/more burst (like master yi, xin'zhao,udyr,nocturne,even twitch) or cinderulk (warwick). The only one that's powerful with this seem to be shyvana because she has a really bad ratio and on hit work well on her q. For making the item more attractive it could work like lyandri/mask that increase instead of magic damage, basic attack damage/on hit (can't increase critical damage but can increase true damage like master yi E) reducing maybe the 4% max hp to 3-3,5% max hp. The on hit effect should be increase by something like 4,5% for auto as melee up to 18% and 3% for ranged (just using the same guinshoo formula 4 for melee and 6 for ranged) (This would keep on eye on champ like twitch,kai'sa,vayne,kog'maw (and kindred?) Who could abuse of it) actually the new guinshoo reward more the true AP or true AD scale instead of on hit scale so a full on hit build seem to be too weak compared to a true ad/ap build.
