Warrior Enchant is still just a stat stick, please consider trading some stats for a real passive
The stats are actually quite high currently so I think with a proper passive they could be lowered to about 40 AD, and considering the other 3 JG items have no CDR I really dont think Warrior needs it, but perhaps it could stay depending.
So now that the stats have theoretically been lowered, lets talk a passive
The first thing that comes to my mind is
Active, but perhaps with a little less bonus movement and attack speed(similar to runic echos vs Ludens)
The other option I thought of would be having it build from
but without the lifesteal and less AD when completed into Warrior(40 AD as suggested)
I think the latter idea is probably the best idea but perhaps someone can suggest something even better.
