Flourite is almost always at over 175 people where the limit is 200. It's the busiest map so I tend to avoid it. Wait until the map isn't as busy, you can check how many people are in each map by moving your mouse to the right side on each page on FeralHeart. Right now there are 196 people so it's going to be hard to get into. I suggest waiting a while until it's not that busy.
