Overall I think the Tager matchup got worse for Lambda on the transition from CS2 to CSE for a number of reasons:
-Lambda's corner carry via multiple midscreen Cavaliers in combos has been nerfed, so it's harder to get him to the corner for higher damage
-Tager's normals got better, which makes it even harder to escape for Lambda when Tager gets in
-Tager's meter gain got better, which means along with his combo damage buff he does a lot more damage than before when he hits you
-Chargeable sledge makes 5D(CH)->Cavalier on reaction much more difficult, and allows Tager to close gaps easily if you aren't paying attention.
just some thoughts
