Don't you think it a bit pretentious to assume that an editor to which you will submit your paper cannot select some reviewers, and that the reviewers cannot possibly review your paper? Just asking...
I always thought that they selected the reviewers. It was when they asked me to select reviewers i was surprised and unsure of procedure, hence i came here, rather than bother the editors. Thankfully most people have been helpful in clearing up why this is.
