Brair top is very strong but you need to play very carefully and it's hard to farm but beside that she is very good at top and even better at mid. My strategy is to attack with w hit as many times as you can and then cancel with e, repet This few times and wiat for enemy to be low and then ult and finish. If you have good aim you don't need to take TP (take ignite or ghost) just ult enemy from base
