Tibbers can literally 100-0 people even if they are trying to avoid him after Annie dies.

How is it balanced that when Annie dies you have to receive hundreds, perhaps thousands of damage afterwards if her ultimate is currently up? Gigantic speed boost (making it impossible to escape) and a ridiculous attack speed, plus AoE damage around it. Literally impossible to kill unless you're graves (who can knock summoned units back for some unknown reason, making daisy useless...).

This could be fixed if tibbers didn't become enraged when Annie dies, or if he just attacks the nearest person instead of hunting the killer down.
