I played Rift around launch, reached 50, did some heroics and raid rifts when they first came. I quit, because what I saw did not impress me at all - only one boss with moving lasers had me intrigued.
I later picked it up again with two friends, when Instant Adventures came. We got bored and quit due to how boring low level was.
My question is, does Storm Legion improve these points? Are boss mechanics any better than before? To me, most of them were far too simple, only causing wipes due to high damage.
