Ash's Shoulder Bash ends upon hitting a target. Try to block off her most convenient escape path when she reaches low health, trading 800 health for a basically guaranteed kill.
Ash's shield is very small and easy to avoid(it can even go throught you ) , when you buy cc immunity item(she will try to move you character), you can easly rush throught it and make it useles, then u can easy deal damage to her and finaly kill
Ash's ult is powerfull and easy to counter(all cc abilities) but you also can make her not even use it, like hook with makoa , torvalds ult , Jennos grip, Shalin's and Cassie's rmb arrow can block her 'Ult jump' or move her ult to other place
