lol, y'all sound like a bunch of sentimental greybeards :)
'In the past everything was better.'
I loved KDE3, and yes, they messed up for KDE4. It's also partly the distribution's fault, for shipping KDE4 way too soon. But I think from KDE5 (.6 something) onwards the KDE team has done a remarkable job with shifting dependencies (e.g. Qt4 was radically different from Qt3, but there's many others), shifting requirements like compositing, wayland, audio+video frameworks, all while keeping the good olde xorg stack fully usable.
It's not perfect, and you might not like the direction it is taking, but all-in-all I'd say it's in a pretty good place right now.
oh BTW, you can change the font of the clock nowadays, just right-click and configure.
