Yes, yes, yes, a million times yes.
The only thing that I ever did on cubecraft after 1.9 and before MinerWare was spleef and TNT run. Now both are completely gone. The only gamemode in arcade that people seem to play after the change is layer spleef and I'm pretty sure most people just accidentally join it thinking it's normal spleef. The old arcade was better in every single way. More games, better games, more popular games (when would you ever not be able to find a game of tnt run, spleef, SSM or block hunt? ones like hourglass and quakecraft might not have been as popular as the others but they're sure as hell better than what we have now.)
Generally, I don't like the change to make every single main area of the games the exact same. Gives everything an extremely bland feel similar to that of Mineplex or something where everything looks as if it's made by a for-profit games company instead of a group of extremely dedicated people making a community from the ground up that is made solely to entertain people and to not rake in truckloads of money from young children's parent's credit cards across the globe.
What was I talking about again? Oh, right. Arcade minigames. BRING THEM BACK. PLEASE. Might as well get rid of the current ones, too. They're unpopular and boring.
