If you pick a character that you hate just because they have a good tier rating, you might not have enough fun playing to put the necessary time in to make the best use of the character. A character with a lower rating might actually turn out to be better for you since you'll practice more if you are having more fun with the character. That is unless you are a purist with absolutely zero character bias who only cares about winning, which is fair enough. Nothing wrong with that. At the same time, if you pick a character that has real problems, one who has bad mus with popular characters, and you just get killed time after time, you might not stay in it long-term either. You could get frustrated and there it goes. So, there is probably a balance of winning vs. fun-from-character. For some it might be 100-0. Others 0-100. Probably a lot of us fall somewhere in between.
It does seem early to put too much stock on tiers. We are still well within the season for nerfs and buffs. I heard Kano was great when MK9 first came out, then he got nerfed to bottom tier. So, Cyborg could get nerfed to D- and Bane could get buffed to S and we really don't know what tweaks will come or how they'll play out.
