I'm gonna make a it of an iffy statement on those Praetorians here, while it's impossible to basicly prove, I'm gonna bet if I took those same Colonial and did something with them, using the same basic conversion idea of Cadian arms and/or weapon swaps, but working to the best of my [URL="http://colgravis.blogspot.com/search/label/Colonel%20Ackland"]abilities[/URL] they'd get few, if any, complaints - at least compaired to what this individual is being subject too.
I think we all love to play against a well painted and modelled army, and most of us who are in the hobby for more then just the game would strive to own such armies ourselves, the problem is we all have to start somewhere, which may well not be winning demons. In our own personal quests to achieve that some people stick GW, some people scratch build, and some people use models from other ranges*, the results won't always meet with applase as in this case but it's someone taking steps on that path. Cristism is good, without exception, but only if it is constructive, how the models or ideas could be improved upon.
* I'd make the exception if no effort has been made at all to convert them appropriately.
