I don't know if anyone else experiences this, but sometimes you can't see the purple/gold lift particles on the elevator pads. When you are rushing to go revive some one or run away from getting killed, it sometimes gets confusing to know which one brings you up/down. Now the problem is mainly with going down as for me, the particles don't seem to be visible most of the time. Why not change it so the pad at the bottom is colored gold for going up and blue/purple-ish for going down? Instead of the way it is now, where the elevator pad colors are both the same.
