Warmog's Armor - Passive Not Active at Exactly 3000 HP
Warmog's Armor
UNIQUE Passive - Grants Warmog's Heart if you have at least 3000 maximum Health.
Recently, I purchased the item on Braum in an ARAM game and had exactly 3000 maximum health. Even while I was out-of-combat, the passive did not activate to heal me.
You should probably change the wording ("over 3000 maximum Health") or change your calculation (Champion. MaxHealth >= 3000). I'm assuming someone may have forgotten to include an '=' sign in the conditional.
Though it is possible that I was technically under 3000 maximum health (i.e. 2999.97) and the display just rounded upwards. If so, this is a clarity issue.
While this is relatively minor, it was rather annoying and should be a quick-fix.
