There's two approaches that can be taken to Centurions for this game: 1) Make them hilariously adorable as Alfabusa said which means they'll really be there just for laughs. 2) Make them incredibly bad-ass as they are portrayed in their Concept Art, slightly taller and not so stocky than their tabletop counterparts, making them feel and function more like a large-walking suit as opposed to a short, fat, waddling mecha-duck.
Well to make a Centurion actually good looking you need only two things ; Remove the crotch plate and take smaller helmets It look like they can actually walk and with the smaller heads it would be less silly
I admit the new Centurians are amazing. However, I think they should be a later addition, much like a 5th race. At this stage of development I think it better for the devs to focus on the main characters types for each race first before going into the new models that have been launched.
I think there are not enough 'NO' in the voting option. It should be: NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO!
The centurions don't look that bad in the codex entry pics, it's just translated very poorly into the actually model, much too bulky looking, almost chubby, and a severe lack of dynamic positioning.
If the game needs these *things* to encourage people to keep playing, I think it's in serious trouble!
