Rope Trick seems like a great spell, but in the last year and change of playing 5e every week, I've never seen it used, and I've never heard a player say, "I'm building a Wizard this time, because Rope Trick is so awesome."
Wizards deserve to have some incredibly useful utility spells on their spell lists. They are, in other respects, the least hardy and the least combat-effective of the caster classes. Ritual casting goes in the same boat for me. Wizards can't empower fireballs, or cast d10+4 eldritch blasts that knock the target back 10' feet on each successful hit. But they can fill that spell book up with as many spells as they can find and afford to scribe, and they can cast any ritual from that spellbook without expending a spell slot. That's their thing, and if it's so overpowered, why doesn't everybody play one?
(I'm playing a Wizard right now. It's the first Wizard I've seen yet in 5e. Or actually, the second, because my first Wizard was dissolved by a gelatinous cube after failing to climb out of a pit a couple of weeks ago. That guy was pretty mediocre in combat, but whenever you needed to something weird, he was your guy. I hope my new Wizard, Billy the single dad and paper pusher from the local Wizard's Guild, is going to live long enough to learn to cast rope trick for his friends.)
