For example, the Azure Whelpling belongs to the Dragonkin family. However, it has Beast, Magic, and Elemental abilities in addition to a Dragonkin attack. Different attacks are strong and weak against different family types. Having a diverse spell selection might increase your chances of being prepared with a strong attack against an opposing team.
Workaround as a player is simply to skip forward past that step in the guide, at which point it has steps for the other quests. I'm still on Bleakrock as that character, so I don't know if a duplicate "begin the evacuation" step exists after you've found all the missing people. In either case, just don't talk to Captain Rana about evacuating until you've completed all the other main/sidequests on Bleakrock, which are listed at the UESP link above.

Frost Death Knights have been through some changes on the 8.2 PTR, focusing on Breath of Sindragosa and Blizzard have been struggling to get it just right. The main issue with the powerful ability is that it takes away a huge amount of resources from the rotation, creating a big gap where you can't do much.

So far i've done almost half in the past 2 weeks or so. I just want to know would it actually be beneficial to do the above tasks? Just all seems a bit too grindy, I feel like I've been wasting so much time doing old content that's not even needed any more... but I didn't mind doing them for the transmogs and such. I guess i'm just asking if this addon is really worth using and it's not suggesting unneeded filler.
