I have some suggestions about the items that should be implemented or changed. Here are my list of suggestions.
Doran's blade: no longer gives life steal, instead it heals from dealing physical damage per hit. For melees they heal for 5 for basic attacks and single target abilities, 3 for area of effect abilities and multi-hit abilities (2 from AOE multi-hit). For ranged heals 3 from single target, 2 from area of effect / multi-hit (1 from AOE `multi-hit)
Doran's ring: No longer gives mana back from killing units, instead it does the same as dorans' blade except it works for mana.
Cull (along with ancient coin): Ancient coin merged with cull instead. I find cull, right now a very useless item so it should be reworked into a support item. So instead of it having that 1 extra gold per unit kill for passive, it will have the favor passive from the ancient coin. So the active would have something like this when it is completed which is called the blade of rejuvenation.
Cull: 3 attack damage
Arrow of accession (NEW): +8 attack damage, +25% mana regeneration, +2 gold per 10 seconds. Recipe: Cull + faerie charm
Nomad's arrow (NEW): +35 attack damage, +10% cool down, +25% mana regeneration, +2 gold per 10 seconds. Recipe: Blade of accession + two long swords. (Reworked unique active)- curse: Reduces targeted enemies tenacity by 65% for 3 seconds, cool down is 30 seconds. 800 range.
Eye of sharpness: +10 attack damage, +200 health, +10% cool down, +50% mana regeneration. Recipe: blade of accession + sightstone. Unique passive - warding: 4 charges of placing stealth wards
Vampiric scepter is removed from the game, along with the bloodthirster. So the items that was built from this should be reworked like this.
Death dance: should heal more on 25% of physical damage dealt and area of effect will reduce to 1/2 of effectiveness.
Bildgewater cutlass: Will still have the active, but it will have more damage to replace for the life steal. The stats gives 10 more AD, and pickaxe will take over the vampiric scepter for the build path
Blade of the ruined king: Should give +40 attack damage, +40% attack speed.
Ravenous hydra: Should replace life steal for 20% critical hit rate, and the splash damage can proc critical hit strikes (Just like runnan's hurricane bolts passive). Tiamat, Pickaxe, cloak of agility
Scimitar: Trade life steal for more magic resist, maybe more magic resist will help, so hexdrinker will replace vampiric scepter
MOM: The passive, will grant bonus physical damage instead, gives a higher magic shield
Infinity edge and Essence reaver: give them 10 more AD
