I have seen the statement made a few times now, that a Necro makes a better puller that a Monk.
Indeed I used to play with a Necro who was a superb puller (MIA these days, the bugger), but I had always put this down to his great player skills and many years of experience as a Necro.
However I have also played with a couple of outstanding Monks (two in the el supremo category, one fast approaching).
As far as class skills are concerned, it seems to me that a Monk should have the advantage over a Necro.
Why is it that many people believe the Necro to be the superior puller? And indeed a number of high level raiding guilds seem to use them in preference?
