5 boxing status in todays game

[StephenMB]

Hey guys... I ran a 5 box around 6 years ago and could do almost all instances... I know I know, its been awhile... anyway, what I am wondering is if they made end game dungeons and such hard to 5 box now. I am not really interested in 5boxing old content and just mauling through it... I am hoping the last few releases in WoW still allow someone to 5 box them. Is there enough new content the last 5 years or so to keep me busy 5boxing the instances for awhile?

Can anyone give me their feedback on this before I reactivate all 5 accounts again? Thanks in advance.

P.S. Anyone recommend a boxing friendly guild out there with a lot of veterans in it that play for the game and not for profit?
