Why do you want something to stay that you haven't even experienced yet? You have no idea about balancing in late game (given you're only level 11) but you claim that a glitch should stay for which reason exactly?
If the game is too hard for you, play on easy. "Problem" solved.
This is either pure stupidness and ignorance or serious trolling. It makes me sad and angry when I have to read such crap like the post of the OP.
From the title a smart person might have deducted from the title what this post is about. If you get sad or angry these feeling are therefore self inflicted. As you obviously like to wallow in these feeling be my guest!
