The GMs suck at that. I hate not seeing any replies at all saying that it isn't possible to implement or something.
Last time a staff member posted in Suggestion (other than Yuyuko), it wasen't done correctly, and Talis had to make a big wall of text apologizing for that member's actions.
Also, some suggestions have been taken a note of; it's just Talis has been doing a lot of behind the scenes work and Dreus I assume has been helping.
One recent example can be taken for the Gunslinger / Ninja dyes. People suggested that for a while, and finally after much testing, it was done. Now, we're just waiting on more dyes, rather than having 10.
Be patient, I've come to learn that GMs DO look at the topics, they just don't comment so that you don't really get false hopes / misguided ideas.
