When level 2 spells are up there are so many more spells players are catching up on from first and adding to second level spells that rope trick gets ignored in favor of just picking up the munchkin card designed tiny hutI don't think I've ever seen the spell actually used. But even then I don't see how it's particularly broken. It's a second level spell taking up one of your prepared spells.
Either the opponents know where you are and can likely deduce that you're hiding somewhere in the vicinity (in most campaigns intelligent monsters know spells exist), or they have no clue you're there at all. In the former, they're going to be on high alert with extra patrols and defenses activated. If the latter you could have found a broom closet to hide in.
@Todd Roybark people commonly complain that fitting in all five encounters in a single "adventuring day" is difficult, you seem to be suggesting that the solution is to include all five in one go then ignore the fact thst the party has ten minutes to leasurely cast tiny hut but doesn't need to because they still have the rest of today's five plus tomorrow's five on the other side of that impenetrable wall of force one way mirror.
