She is deadlock but instead of a stun its a flash and instead of a slow she has a molly. another no trip sentinel (the wall doesn't count). the only real difference is that Deadlock has a lot of white while vyse has a lot of black
But in exchange for that they're useless for entering site. Her ult is crazy good to be honest and at least she can use a flash in entry. Meanwhile the most cypher can do is put a cam down which in most cases immediately gets broken. She for sure can stand on her own as long as you have half competent teammates that can realize people can flank.
but the character is also similar to KJ/Cypher, the wall acts as a trip (cypher trip, KJ bot/turret)
she has a way to stop entry (KJ molly, Cypher cage)
she has a flash in replacement of info gathering (replacing something like KJ turret/Cypher cam)
so she still brings most of what hard sentinels bring, replacing some info gathering for a stronger site execute style of gameplay
