Warmongs i believe is an item that should be removed from ARAM
is absurdly powerful and frustrating to face on ARAM. HP Regen is a powerful tool in the ARAM mode and when you have an item like this that can grant infinite HP regen to almost any champion in the game at the 15-minute mark then there's an issue. No matter what the team comp, any champion can pick up
be it tank, mage, ADC, whatever and become an utterly unkillable machine. It's not just strong on tanks, ADC's abusing this item is just awful, mages with long range poke is just as bad. I'm not saying make ranged stronger on ARAM but I do think that if you aren't going to remove it you should tune it to be Melee only.
