Problem with Argent Tournament dailies

Hey guys!

My character was originally made on the alliance side, did 2 of the total factions of the Tournament dailies there, no problem. Switched to horde for a couple of weeks, did do some dailies there aswell I think I've finished 1 more faction meanwhile. After that I came back to the alliance side and ever since then I can't take any quest from the remaining factions that'd be needed to complete every single one.
I've read in an older post that a server reset might do the trick, but I'm curious if that's still the only solution for this "problem"?
I've been checking it every 1-2 days for some weeks, seeing if they'd come back but still nothing.

Thanks for any reply in advance!
