M'kay, I should have made this a little bit more clearer before. Sorry my fault.
What I mean is that all of the canon ships should be kept because otherwise the game wouldn't be the same. The sister classes however that cryptic developed such as the cochrane, quasar, vesper; many of them should look more futuristic (as in 25th century or late 24th). They should look sleek; more eye catching and advanced. A lot of those sister vessels however are bulky looking, not eye catching or futuristic looking; hell they don't even look like they were built to exceed warp 8, let alone travel at slipstream.
What would be nice to see is the non canon sister starships look more eye catching, more advanced and futuristic and sleek.
Oh and by the way, I think the community manager a brilliant person who goes beyond his job at cryptic. Good on you mate.
