In normal and nightmare, high level IM (29+) and thorns does more damage. However in hell, due to the 50% physical resist, amp+thorns is far superior. Amp cuts phys resist from 50 to -50 in hell. Even a lvl 50 IM plus thorns merc won't beat AD and thorns merc. So would you try to get an insanely high level of Im or just stick one point in amp? The answer is obvious. :)

I think the thorns merc was capped at level 17? If you can bring it above level 17, IM simply doesn't stand a chance against amp.

I personally don't think you should cast IM after normal unless you are desperate. In 90% of situations, the other curses are infintely better. Not to mention is not exactly party friendly at all. A lot of people don't like necros because the IM/golem cheese isn't godly anymore. Truth is, you can't depend on any one skill to survive. The necro is a perfect example of it. None of his skills alone are particularly effective, but when used together are much, much more powerful

Not saying that IM is useless, but the necros that spam it in public games cause certain feelings.
