What the heck level 745 and 315 has become very hard

Generally levels have been made hard or impossible to pass so that players will spend gold bars to overcome them. That is how King make a profit. More specifically I wonder why are you asking about two levels so far apart?

There are many more legendary levels in the episodes between those two levels, which are as impossible and hard as well, which is why I asked. The purpose of legendary levels is that they will block players and make them use their gold bars or boosters, such as a UFO, to pass. That is what makes them legendary. If moves were increased and layers of blockers removed, then they would be reclassified as "hard" . That would undoubtedly make the game more fun for more players, you are right about that! But it would give King less of a profit and that is why I fear that legendary levels are here to stay.
