"Class does a lot of damage with all of their abilities so they must be a bad class."

Non sequitur much? Death Knights may have a fairly loose rotation while leveling, but that's the point. Leveling shouldn't be a difficult task. Further, when you reach level 80, Death Knights (and in fact, every class) open up and expand their rotations substantially. Frost DW requires a pretty high degree of awareness to pull off - responding to Killing Machine procs, Rime procs, Death Runes, Diseases, and all the boss mechanics? By no means a faceroll.

Before you condemn a class as "terrible" perhaps you should actually understand the class. You're entitled to your opinion, but your opinion means nothing unless you have some logical backing to it.

I'm sorry if my opinion hurt your feelings. Here's my logical backing.

If a class puts the player to sleep while leveling, then it is a bad class. I absolutely refuse to waste time on leveling a class that only gets interesting at 80 which I could be spending to have fun with a more engaging class that actually has a semblance of gameplay from the get-go (like, you know, warriors). Give me a level 80 DK and I'll try that out, and may even agree with you. But unfortunately Blizzard makes DKs start at 55, and that is just about 25 boring levels too low.

Deathknights gain so many abilities in such a short time, from the one or two buttons they have at 55 to a loadout comparable to other classes at 60. But guess what? They're all irrelevant. The only reason you even need more than one button on your bar is because the rune system keeps you from spamming that one button. So instead you have three buttons, each consuming one type of rune. Just mash whichever lights up.

Of course there is synergy between diseases and abilities, a certain order in which to use them presents itself just from reading the tooltips. But whether you keep that order or not is irrelevant. I actually tried it out; the end result is always the same. You don't even need to use any runic power, because those abilities again do exactly the same thing as your rune abilities. No thinking required, no decisions necessary. It doesn't feel like you killed your enemy because you were playing the game and did something cool, but rather because... well, no reason at all really.

And that's why I dislike leveling DKs.

The mob approaching you isn't failure, Rossi! It's just a progress bar that's fighting with their health bar! It's *fun* to work to make the HP bar win the race to 0.
