I've been playing Bane since day 1 when I had to figure everything out on my own because it seemed like no one was playing him, and while he has some match ups that I think are borderline unwinnable unless you are significantly better than the opponent, he does fine against quite a bit of the cast.
I don't do very big combos with him, mostly just simple BnBs into Body Press, or just Double Punch/fd2 overheads if I think they're going to block low. I also very rarely meter burn anything, because the non-MB versions of his specials leave the opponent at the perfect distance to make them guess with high/low/Body Press, which immediately leads into another guessing game if it hits, and having a full bar of meter for super or winning a clash is better than what you get out of MB specials imho. These tear people apart a lot of the time in my experience, because it's a lot easier to guess right as Bane than it is to guess right against him. So, I guess try that if you aren't already.
He also gives a giant middle finger to most characters pressure games due to venom. I think Bane is a strong character, he just has a handful of godawful matchups that also happen to be against popular characters. He reminds me of Zangief in that way.
