This seems to mesh with my experience. The higher level of the bad guys involved the greater the risk of grind. 4e is surprisingly intolerant of what level enemies to use to get the most fun fights (beating up -3 guys is not fun either).

Back on topic I have also noticed "controller grind". Monsters that deny the PCs effective actions at the cost of damage output can give grind. The most defining experience I had was fighting a Lamia with an AOE stun on a recharge IIRC that did no damage. Once we had disposed of most of its allies we were all stunned every couple of rounds while it did a little damage back. Then we would nibble it for a while before more of the stunning. This encounter also suffered from it being higher level than the PCs & not very well designed in composition.
Fighting anything that dazes stund & imobbilises can be frustrating - a little control goes a long way IME.
Other horrors have been regenerating weakening incorporeals ....
I suppose that is another potential element to avoid. High level monsters (Elite or not) will hit more often. If the monster has a single target attack that does heavy damage, no big deal. It will probably not cause too many problems due to healing surge availability. But area of effect attacks that do no or minimal damage yet inflict conditions like Stun, Daze, or Immobilize can be extraordinarily frustrating.
So I suppose we can add X+3 Controllers as a Grind risk. What monster is the 'regeneration + weaken + incorporeal? I would have to guess a Lurker of some form due to Incorporeal. What experiences do you (or anyone else following this thread) recall from fighting Lurkers that are a higher level then the PC's (beyond the infamous Black Dragon example, which I would blame as much on Solo as on Lurker)?
