A word of caution using glitches on purpose. They just banned a ton of accounts ,and posted a warning saying not to intentionally engage in exploitation of glitches ,but rather report them as soon as possible.

To the point of blm ,and smn being weaker I assume they are once again following a cue from blizzard who would actively nerf classes to the ground during new content to force people to try new things. This sounds like a disgusting practice when you consider we pay them to sometimes ruin our favorite jobs, however the vast majority of players become discontent playing the same thing for long periods and venture elsewhere. When you consider it that way it's really just self preservation.
