The removed parts of ARR MSQ didn't save any time at all

Others said they didn't want to learn to play a raid synced down to level 50 toolkits.

So you go into it with your level 50 toolkit when you're level 50 and you're used to having that toolkit. It's no different to clearing a dungeon at the same level - and many of the dungeons have similar or worse gimmicks to learn than CT does at this point.

As for social anxiety from the larger group, you're ultimately still in an eight-man party and don't interact with the other two groups at all. Almost all mechanics come back to "fight X with your group of eight" but there are three Xs on the field.

Have you actually, personally played CT at this point or are you hanging back dreading the idea of "raiding"?

Just think of them as large-scale dungeons. It's what they are. If you're not confident, your group will probably pull you through and you don't have to touch it ever again.
