Time to recall Guitar Heroes World Tour?

Every time I play Guitar Heroes World Tour, I insert a swear word in every sentence I form. It’s true, the overstrumming, the insensitive drum pad and the loose whammy just give me a hell. Instead I was using GH3 guitar and about to sell this whole set and replace with Rock Band. But after reading this fixes for GHWT problems, I realize I am not the only one having the problem and they are all known common problems. Where is the quality control? How can they ship out these “broken” products? I seriously thinking of tossing Guitar Heroes aside and get Rock Band instead. But before doing so, I’ll try those fixes first and we’ll see… Sigh, weekeend project for fixing instead of playing.
