Essence Reaver [My Suggested Changes]
Turn Essence Reaver into an early game purchase by something like: Long Sword + 340g = 700g The Stats will be: 10 Attack Damage and UNIQUE Passive of 2-8% of your damage dealt by basic attacks will grant you mana This will solve early game mana problems for mana reliant AD champion, specifically for marksman, where this item is suppose to help.
The end game upgrade will be what the Essence Reaver gives now just with a slightly different name and item icon with the build and stats being: Essence Reaver(700g) + Vamperic Scepter(800g) + B.F. Sword(1550g) + 450g = 3500g Stats: 80 Attack Damage, 10% Life Steal, 20% Cooldown Reduction, UNIQUE Passive of 2-8% of your damage dealt by basic attacks will grant you mana 20% Cooldown Reduction is so this item is more like Grail just for Marksmen instead of Mages, it just makes sense that a high mana sustain item should grant high CDR as well
