Bears are already retarded enough.
They almost 100% of the time murder you, and when you're abotu to get murdered, you get lagged to shit.
Now they run.
A bear in real life would NEVER run. It would stay, maybe it might back off, but really.
I'm not bitching about "ono me frend died its such an bad los" when I say this, but bears will fucking SPIN AROUND AND CHARGE YOU.
It's like, "You want more bitch?"
Seriously, that's stupid.
Besides, you need like really high UA to actually kill it when it runs, and good armor, or else it'll just gobble you up.
