This is getting so repetitive. Eric, we are not wanting to re-define evolution. We want to modify the rules to include all Pokemon who do do something competitively identical to evolution. Nothing else. You can't say we are breaking any rules if we modify them first. And we should really stop asking "Why stop at changing this rule?" because the answer is quite obvious; because no other rule has any case remotely similar to the evolution rule. Little Cup's rules are outdated. They were made when there was no other process to change between pokemon except for the nintendo definition of evolution. The main point is: Rotom's process is competitively identical to evolution. We are a competitive community playing a competitive metagame. In fact, I'd go as far to say that it would have to be admitting that Little Cup isn't really competitive "oriented" if we don't include Rotom because of non-competitive technicalities.
