It seems quite stupid that Nexon would release those on the Ereve training maps. Only Cygnus Knights have access, and the maps are comparable to those on Maple Island... how can Nexon expect those monsters to be anything else than a huge annoyance for the new characters?
You will have to avoid them the best you can or wait until after the event where they'll be removed.
The term "wall of text" only applies to ignorants who do not bother to read their opponent's mostly perfectly valid arguments before immaturily attempting to counter them.
