I wasn't supposed to post any message in this section again, but... I still care about what happens to MD so here goes.
I strongly dislike the idea of that kind of requirement.
I don't have any alts myself and I'm not going to create one ever. I have only my main account and that's really enough.
And that should be enough for most of the players. In my opinion, the true problem which leads to alt abuse is the existence of alts.
Seriously, how many alts were actually meant for creating another character for role playing needs? 10 percent? Doubt it, probably even less. All the rest is used for storing additional creatures, goofing around and for all kinds of so called "alt abuse".
And now you're planning to mess up the gameplay even more with those restrictions. So me and many other players at mp3 and mp4 levels, who don't have alts and don't abuse any MD rules will have to face the consequences. All the bored mp5s who send their drachs and other monstrosities to their mp3/mp4 alts will be fine, as their mp5 main won't face any restrictions.
I'm at mp4 and don't want to progress to mp5. I have few Angiens which were obtained legally and I put a lot of time and effort into training them. And now me and other players who don't have any alts are going to be punished with severe creature downgrade because of abuse done by others?
Excellent...
I've noticed that most of the ideas and changes are only mp5 friendly.
Mp3 and mp4 just need to quickly get to mp5 and be farmed and grinded into cat food by the "vets".
