There's like 4-6 main rank whores who want zm only, the rest are open for ze or zm. If these rank whores knew the ze maps wouldn't mess with their rank, then maybe they will actually play, and help with ze. Instead of sitting in spec, telling everyone to RTV, and actually help make IBIS ZE a fun place.

Let's face it, these rank whores are rank whores simply put. But they know how to play, where to defend, how to defend. If they knew getting tagged, getting caught, dying in ze wouldn't fuck up their rank, they can lead to higher success rate in wins for ze maps.

ZM is where the points rack up. Build a decent cade, trap a zombie, get headshots, kill them. Bam. Be a starter zombie, tag all those who are still running around, bam more points. Not much of a challenge.
ZE, just run, defend, get to the next level. It's fun, it's challenging.
