First of all petitions are useless. Online ones even more so. They won't change anything.
That aside, I HIGHLY doubt any decision is based solely on something posted here. They have systems in place to monitor how people play the game, that feedback plus reviews posted around the web give a far better idea of what people want. The forums are usually mainly the vocal minority, plus a few people who are bored.
If a change is made, after there happens to be a lengthy thread about it, it's not because they looked at that thread and decided they must listen. It's because it happens to reflect what people want.
You're not alone. The OP is telling Bioware to stop listening to the forums, in a thread on the forums.
