I'm not really sure where this idea of "let's kickstart something to get it implemented" came around, I agree with Noctover that this is a precedent that needs to be put to rest somewhat.
Kickstarter is a great way to get projects funded that would otherwise not be, and gets things off the ground for a lot of burgeoning studios or independent creative teams. There's a lot of good that it brings, and it can be the make or break of that "next big thing." It's a crowdfunding platform. While it's an important factor, you have to understand that monetary cost is not always the only reason that stops something being present in the game right now. It could be balancing, technical limitations, lack of meaningful gameplay for that feature, or the value that it adds to the game is too little versus the work required to implement it... so priority is a lot lower than, say, the core improvements or 2.4 or whatever the future holds. It could also simply be that it's planned and being developed, you just kinda have to wait a little bit for it. Many reasons beyond simply funding, which is about all that Kickstarter can solve.
