Rework Tenacity
Tenacity, currently, is crap. It doesn't do much and with chain CC, I'm screwed anyway. So why not rework it to this:
After being effected by CC, a champion is unable to be effected by CC again for the duration of their Resolve buff.
Tenacity grants Resolve where: 10% Tenacity = 1 second buff 25% = 2.5 second buff etc.
While the Resolve buff is active, your champion does reduce damage for the percentage of Tenacity they have. The Resolve buff comes with an internal 2 minute cooldown. This cooldown is unaffected by CDR.
and
. Sometimes, I'll try and root one of these guys, only for them to get out of the root before the spell animation finishes.
, as that just makes physical damage champions with CC that much better. I'd rather it be on a cheap, global defensive stat item. Like, say, a new 800 or 1000 gold item that grants like 250 Health or maybe 25 Armor and Magic Resist as well as 25-35% Tenacity. Then maybe have it build into a good late game item.
