Every Champion that is on a killing streak will give their killer extra credits to spend. If you are on a streak SOMETIMES it may be worth jumping of the map before Lex can make you his retribution target and gain even more credits.
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.
You do not want to duel Maeve as her combo WILL one shot you. Stay away from where she likes to play unless you have an ally who can kill Maeve first with you.
Assuming Buck hits you at point blank with all his pellets in the head, he will need 3 shots to kill you.(2.8s) This will never happen. You can knock buck down to 500 HP with the Daggers+Pounce+Daggers combo (about 2s). Easy kill from there.
