You are still clearly not getting it and your examples just prove my point even more. Kat is NOT a SUPPORT and does nothing to SUPPORT the team. She is a pure damage champion that is truly meant for mid as an assassin. YES you can bring her top because for the fact that she does Damage and is basically the same as mid. EVERYTHING is wrong with Kat support for the FACT alone that SHE IS NOT A SUPPORT. I really don't understand why you are not getting this through that thick skull of yours. KAT IS NOT A SUPPORT.
You going Kat support is like me wanting to go Soraka ADC. She's clearly not an ADC and has no abilities to benefit her in the ADC role.
I would understand a little if someone brought Kat jungle and said they were breaking the meta and trying it out because she does DAMAGE and DAMAGE is viable in DAMAGE ROLES. She might get destroyed and put far back in jungle but at least shes doing something that she is able to, which is DAMAGE.
There is a clear difference in "Breaking the meta" and making stupid decisions. Bringing Kat jungle would be breaking the meta. Varus mid would be breaking the meta, Corki mid would be breaking the meta, rumble jungle would be breaking the meta.
