This Thing You Call Aggro.

The pet is always +1 target.

You then say that warlocks pay attention because of applying DoT's

Curses. DoTs are dangerous to use no matter what. A lot of bad hunters try to open autoshoot with venomsting, which is bad in many ways. Curses however don't interfere with CC options, and can actually be applied on top of CC options Except freeze trap... curses may break that, I'm unsure. need more testing with that.

I've played with clueless warlocks, just like clueless warriors and priests and hunters and and and... 

I think warlocks are easier to play ineffectively. My arguement is that the skills, and perspective lend toward warlocks to watching the entire battle intimately.

Better players will learn to naturally do this, but in different forms. As you've witnessed, the priests spoke up about what kinds of damage and rates are taken, buffers/debuffers with what affects the party best against mob types, and many forms of aggro and direct crowd control options.

Priests, Druids, and Mages generally don't dispel and remove curse enough alone. They cannot. They're too busy fighting and healing. They need ribbing.

When foreknowledge comes into play, I don't consider it active attention. That's passive reactionary knowledge.

Druids also have 2 forms of CC that you ignored. 

I love root outdoors. I love sleep too. I must say, I slacked off forgetting to mention these. Sleep's great against elite dragonkin and LBRS spiders in particular. Oh, the hunter's pet in DM west undead upstairs.

Not enough druids are encouraged to use their cat form humanoid tracking though, and I'm glad that one was remembered in the OP.
