for what reasons are necros known to be bad at pvp?

[qzar]

I wanted to play one before someone talked me out of it.

Now after wasting some time with other shit I am starting one anyway.

Why are they bad at pvp? Can't we just root and lifetap spam with added dmg from a pet? Sounds better than a handful of other classes.

And I know the cast times are long on most things, but in team pvp I can imagine it working out for them.

Is I wrong?

At this point I don't really care anyway because I love the class but I wanna know what I am in for in detail if possible.
