Sleeks were the exception in my experience. To be honest though, finding something that is bound to my characters pfile isn't that big a deal. I've found all the sleeks I know by myself and I also don't tend to complain all that much about them. Further, no one has any qualms about sharing sleek info because they know that another player knowing the spot isn't going to cause said sleek to suddenly hit its limit.

My problem is with limited preps, particularly potions. I suppose this can also extend to a point with limited gear.

My last comment on the subject will be to simply remind everyone that finding all this stuff yourself is the best way to do it, even if it requires you to try and heard a bunch of cats behind you into an area explore.
