Played a few rounds of Gold Rush this morning, and found the maps to be pretty fun.
The idea is excellent, but the cart's movement could be adjusted more for the defence's advantage. Some parts of the map, are annoying in the sense that the attacker's can get behind the defenders, on one way routes (as the exit is raised only letting scouts through).
Main thing that annoys me is
a) glitch which makes medic invul 24/7, therefore allowing himself to draw all the sentry fire and heal team mates in the opposition's base. Dunno how something like this got past testing.
b) the foreseeable stat padding to follow with all these new unlockable weapons. Already two of my friends on steam have got all medic achievements and ludicrously high scores with that class (in the thousands). I hate to think what will happen when the other classes come out. Weapons should either be all unlocked to start or unlockable through time and not stats or achievements.
