I pointed this out in one of the class system whining threads already and still am backing up my opinion;
Class system for captain and skirmish, customization(warband-like) for TDM and siege. I said this like three times now
.
I agree class system for tdm and siege is bad because it limits the fun and tdm and siege are fun modes, but class system for skirmish and captain modes are very good decisions from TW, just needs a little bit more customization, like a 3rd perk or something or more weapon choices.
