Just had the joy of playing against post-rework cass
Level 6 and is already faster than me with tier 1 boots, easily outranges short-medium range champions all game and cannot be engaged on at all because of ult after 6, rushes a rylais and immediately becomes 100% invincible against melees and other short-medium range champions with no ability to engage on her OR escape from her if you get hit by a single one of her [near-instant-cast] abilities. Swifties don't even help.
Am I missing something or is there literally no counterplay to this champion at all if you pick something that doesn't outrange her?
