I suppose I misused zed and fiora, though my issue remains. Bruisers like jax, diana, rek sai and lee sin all bother me a great deal.
I have tried to kite them, but most have decent to great gap closers, movement speed items, and active items that help them catch you; add flash to all of this and I just don't see it. As evidence of this, I have seen countless lux, zyra, lulu and yasuo be completely destroyed by these champs. That is why I am confused and frustrated; these bruisers do NOT have the same issues normal bruisers do (Riven, malphite, Poppy, Xin xiao and now that I think of it, fiora).
Take xin for instance; xin is easy. He dashes at you to slow you, you cc him with something and move out of range. Even if he has botrk you can stay far enough away that your cooldowns will come back. You cannot do this to jax.
Jax jumps at you, you move out of - he stuns you. You flash away, he flashes. He either jumps again or uses botrk to slow you down. You are dead.
How do you stop things like THAT from happening? Do I try to cc him before he lands? Do I flash the minute he jumps? Any advice at all man, any would be welcome.
