PLEASE include to the next update to U4eF a disable option. I mean a server-side menu where you can turn several professions off. Especially the Wizard and the Scientist are able to slow the game down extremely on low-end machines.
Also there are several maps where some professions (again especially the Scientist and the Wizard) lead to 0:0 games. Scientists are able to build so many autocannons that the falgs are unreachable on some maps.
With that option you're also able to make a real theme for a server (for example fantasy-style maps and only professions like the Kensai, Archer, Crusader and Wizard).
I really enjoy those two professions (Scientist and Wizard), but sometimes I would prefer to turn them off.
