>Rot can be flee-return spammed, making it ultimately very hard to stop indefinitely (especially combined with blindness).

Unless the shaman loses concentration, you can't spam rot. Assuming the shaman doesn't lose concentration, the target gets either rot or the wasting disease. You can't rot someone who's already affected by the wasting disease.

A/b/s for necros + wraithform?

You don't have to get all your +con stuff immediately after being looted unless you expect to fight a shaman immediately after you unghost. And it's not impossible to find some +con gear that's relatively light and fits in a sack. Esp. if you're good-aligned.

Avoiding assassinate means you have to modify your behavior 100% of the time. Avoiding rot means spending 10 minutes gathering a few items, then carrying around an extra ~15 lb.

Rot doesn't prevent quaffing potions either.

I'd disagree with this. Depending on your class, if a non-moron muter hits you with big neuro then you're dead 3 times out of 4. Maybe that's your experience with rot as well, but trust me- it doesn't have to be.

When you die to rot, typically it's in a place of your choosing. Meaning you can run back and loot your corpse before the shaman does, which saves you the time of having to regear. Die to assassinate, cleave, offense shifter, etc. and you're probably getting looted. Add that to the "time to recover" when you compare those skills to rot.
