[Fan Rework] Zeke's Herald (melee only)

Here's Zeke's Herald my way :

It's designed for 'Support-Junglers', melee Supports and Fighters. It offers Health, Attack Damage and Lifesteal for one self, and team-presence based Attack Damage and Tenactiy, meaning if you're with your team you are stronger. In return you heal your team for 10% of all damage you deal.
I could actually imagine this being good on some Assassins as well. Your team engages and you swoop in to deal your damage and heal them.

It starts at about 2050 gold value and is fully cost-efficient if 2 allies are present or if the passive or 10% tenacity or the passive and 10% tenactiy is 172 gold worth, since the passive doesn't heal you, only others.

Here I say it costs 2400 gold, but I think the price could easily go up to 2700, since it does seem a little bit too efficient. Alternatively, the Aura range would have to be kept extremely small.
Just imagine a Fiora, who has this and . She could heal her whole team for a massive amount just by clicking R.
