At least having Jak at 999 redeems you a little bit. Otherwise, you have lost some of my respect for using Kratos in Ranked.
NOPE. Just had a match where you took advantage of an AFK person and used the overused Kratos cookie-cutter combo. Nope. You should be ashamed of yourself.
I have to resort to kratos in FFA to help me maintain my black belt? I mean like... He's only level 247
Best way to maintain Black Belt (or any belt): STOP and go to quick matches.
I'm just gonna say no, because nearly every one in Ranked will spam like mad and play only as the most OP characters. I personally carry no shame when it comes to Ranked, however in Quick matches I'll be fair.
EDIT: Just read what JushtFinisht posted -- okay, you should feel partially ashamed.
