No, I think it's OK. If it's the hover tank, it's rather well known, it's actually been released, it's just not in any maps (if you search your FS folders there'll be a Hover Tank folder in there somewhere).

These guys?

Turak IV sounds like an interesting map concept - perhaps it could be one of those 'last stand' map where you can't hold back the enemy, but still have a chance to win the round if you hold each control point for so and so long?

Where do you guys know them from? They were new to me when you mentioned them in this thread. Are they in a game, novel, comic, or something else?

It's mainly the fact that the design of the vehicles for that game are very poor in general (Most likely because of the type of game it is, I guess you don't get that close to the vehicles in a RTS game and therefore the design doesn't have to be as tight) and just tend not to have the same look, feel and attention to detail that the movie based vehicles do. Other EU content we may use at least approaches the same level of design where as we feel that content from EaW does not.
