Casual here, I've also noticed that the difficulty was ramped up in this expansion, instanced content is more stressful for me. SE also took away the option to turn off bloom (it was a part of glare) in 7.0 and all the shiny boss effects and lights give me a headache.

I used to sub every other month to keep my house but I gave up on it and only resub once a year to catch up on the (mediocre) MSQ. I like this game but I guess it's just not for me anymore.
