Not all supporters live in, or near Cardiff, so a ten minute trip home is not the same as a two hour trip. You'll never going to please everyone.
Even if you live fairly near Cardiff (eg Newport), Public transport can make for an awkward long homeward journey.
Sunday's @ 6pm, is great as there are buses and trains to choose from, but home games on a Saturday @7pm, mean unless you get back to the city centre before 10pm, you are left with only the last bus @10.50p or train @11.20p, followed by a taxi home from Newport.
So if the club went for a Saturday home fixture I would hope that face off could be brought forward to 6 or 6.30pm.
All in all as Wannabe etc have said, "if it ain't broke don't fix it"
