Don't find it that hard tbh, sure the first time there was running the wrong way maybe once or twice, but only took 1 clear to memorize the place and where to go for which bosses.
I also quite like the fact it has no teleporters tbh, they are not really needed and doesn't take that much time to run back to a specific boss. Everything is central from the start of the instance leading to the 3 different wings with blackhand entrance right at the instance entrance as well.
