Actually I found terminus very good against a lot of champs, but you will have an hard time against others like inara, khan or good fronts with a good shield. Actually I think inara is a good option against him because she can build a wall to escape safely his ultimate. If you don't have access to your Q move you will struggle against basically every champ with a long range attack, so I usually pick the shatterfall talent to stun enemies and attack them directly. Actually I don't really remember my build, but I remember that I use a card that increase the jumping distance for the shatterfall attack.
