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
Andros will typically be using a load out with the card Abyss Walker which basically heals andro whenever he uses nether step this means that Cauterize is good against andro. If you play against a team with andro and a healer caut is a good pick
Once an Andro tries to flank you, you should try to get one or two shots on him, then use your seedlings. He will most likely use reversal which gives you time to escape. This works best if Andro's escape ability is on cooldown (after he has flied)
