Just wanted to give a heads up and make sure everyone is at least doing Looking for Raid dungeons queued up as your team, the mechanics are super scaled down and there shouldn't be any problem succeeding in these situations.
I really need to do Gul'Dan but everything else Legion has to offer been able to do without issue.
Luckily enough as well the guild I am in that Void is also in actually appreciates Multiboxers and had me tag along on all 5 characters for a nighthold normal run. Didn't have any issues on all of the fights up to Gul'Dan to which I had to log for the night.
Being a ranged class makes a lot of this smoother and I imagine the other teams should work as well to a certain degree.
