I gave it heal reduction resistance because the Mechanical Heart comes with a HUGE cost (25% of your current HP is no joke). I feel the Heal reduction Resistance is an appropriate benefit for the cost. The Cost is so high because it gives 1.5% of your Max HP as regen (which is more than any other item offers) and it can be pretty powerful by itself, so I wanted it to feel like an item you had to really put some thought into how and when you use it instead of just spamming it off CD.
i feel mechanical heart's base stats are way too strong, every tank would just buy this item for base stats even if they cannot use the active because +700 health and +1.5% max hp regen is just ridiculously strong (for reference, 1.5% maxhp/s is only .5% off from being a permanent + in combat fortitude)
The stats I used were initially based off Colossus, but it trades the Bonus Weapon damage for even more HP. The Health Regen is there to make it even possible to use the active and is a more situational Active item than Colossus (not everyone has charged abilities), which is why I felt giving the item 1.5% Max HP regen was necessary. I will point out that if you are using the Active on CD it is very close to a net negative Health regen.
the issue isnt the regen number rather that its +2% maxhp regen during fights with 0 conditional, and also like i said the active being net negative doesn't matter at all if you just use the item as a stat stick (which it would be better as just using as a stat stick which is it's own issue)
