However if you play another maps this became less important
Erm, no it doesn't. It's a problem on ALL maps. It doesnt affect just gow lol. HSC, FOC, maze, AYN, they all have the same exact problem. A maphack is a maphack is a maphack. Fixed order is essentially a maphack in a different form and it's affect doesn't get mitigated simply because you change maps.
In fact it gets WORSE because most people won't know the map which gives those that DO know the map fixed order positions a MAJOR advantage. That advantage is lessened the more people know the map. Your answer to use a different map is like a "I'm going to say I'm an idiot without actually saying I'm an idiot" type of answer lol.
The only map not affected by this are the tiny 2-4player maps such as NWTR, xmarks, etc where people would know where you are anyway by way of map design. And those are ALWAYS gimmick maps. NWTR included and thus boring.
The other problem is that this version also suffers from level hacks, spell hacks, building hacks, and maphacks because all the data is still client side rather than server side. Anyone with a memory altering app can hack this to pieces. The old DOS version hacks all work on this version with a few location changes.
Dellam would feel right at home with this one, especially since there is no build in screenshot, recording, or banning player capabilities. In its current state, it's only designed for campaign play.
