Jenos is very flexible and can fill in many roles (except frontline) with any loadout. Try to find his play style and adapt accordingly.flanking? Group up. Damage? Flank him in a group. Healer? Cauterise.
Torvald's Nullify ability relies on Line of Sight. Breaking Line of Sight with Torvald will cancel the Ability early and make him wait for the cooldown.
Buy haven, even that 7% reduction on all shots may mean that strix must take 3 shots at you instead of 2. This is massive since you have way more time to attack him. Buy nimble since it increases your movement speed making it easier to strafe.
Pick champions who are midrange or short range since strix will have to move his scope much more to keep up with you. Good champions are Skye, Jenos, Viktor and Tyra. Since they have massive DPS short range and their drop off is not that bad.
As Lian you always want to save your special abilities for Maeve. If you do not save it, Maeve will kill you in one single pounce, except you are double as good as her in personal skill. YOU are NOT a Maeve counter, so do not act like you're one.
