She's a skill champion! With enough practice, she's very, very strong.
Your cs is a bit off, check your jungle pathing. Always before going b, or before ganking think "is there something where I can get more gold from, before I move on?"
For an example, you just kill mid lane. You're half hp, with 2k gold. Time to go b!
No. You check your camps. Is there raptors? ALWAYS do them when they spawn (if possible). Never leave camps stand.
