I bet it will soon enough change by a live update. on a side note I think they should implement SjShane's idea so every map has a fair chance of showing up.
"If ND won't patch these maps into the game, the alternative is to remove the toggle, and make the Map Pack Bundle the only downloadable version on the PS Store. Then turn the default pool off and have a pop-up saying "Download the DLC maps to play online" when ever anyone tries to play without downloading the maps.
Booyah! One giant player pool with less lag, and all the maps will have a fair chance of showing up."
I played this game again and tbh it came on the voting screen only two times, both times it lost
If it's not as bad as LU or Airstrip, it's fine IMO.
It actually seems to come up often near the start of playing for me, but doesn't come up later much after that, even with DLC off.
I usually play it once every time I come on to play UC3, but it's not ridiculous. In fact, none of the levels have a ridiculous chance to come up often in TO or Plunder anymore. I'm liking the variety.
