I also played the MH games since the very first and guess what? I happen to think the franchise has never been in a better place. Most of the streamlining Capcom did removed tedious time sinks rather than actual complexity.
Case in point, the removal of Hot/Cold Drinks in Rise, which were about as interesting as BG3's current supplies to long rest system.
I was thinking more of little things like "Extracting plants taking a 6-seconds animation rather than being instant" or "mining having to go through multiple seconds of repeated gesture rather than just one single short animation".
I didn't think hot and cold were so terrible to deal with, honestly.
