Changes to Manamune
YO RITO are you guys going to change manamune during the adc item pass? Only like 4 champs build it and tbh it seems kinda underwhelming; I know its supposed to be a poke item but whenever I build manamune I feel like I never do enough damage and it feels like the pay off is never worth the investment and lane pressure I lose by going tear as Urgot/Ezreal. A few ideas I have are
$
Bonus magic damage on autos based on max mana without draining mana.
$
A grail passive that drains your mana on autos but gives mana back on minions (Ranged only)
$
Adding a mini-manamune like you did with Bambi's cinder but make it ranged only
$
Make a baby essence reaver and combine it with tear to make a new manamune
&  Also you guys have any ideas for essence reaver you wanna share with us yet?
. Bam. Early mana sustain purchase that doesn't solve ALL of a champion's mana issues and actually is a source of CDR with currently just pops out of nowhere. Problem solved.
