@Miskos: Plenty of ways to explain that:
 * Tempesta volunteered, rather than being sent
 * Tempesta drew the short stick and thus had to go on the boring mission
 * The others weren't just meeting with nothing to do, but had their own missions, only they were even quicker and easier to resolve.
 * They somehow knew of Laxus and his gang being there, so sent someone strong to take care of the mission
 * They overestimated Yajima
 * Yajima isn't really finished yet and turns out to be quite strong next chapter
 * Killing Yajima is just a "side-errant" for Tempesta, with something really difficult being the primary mission

Should I go on?
