During the fighting festival arc Warren couldn't even cover the entire town of Magnolia (he couldn't reach all the way to the guild from his position) and now he's supposed to be able to reach all over Fiore?

Wendy my dear, I think you are overestimating his abilities a bit there. Even with the timeskip and the pre-GMG training I don't think he can call all over the entire country. Maybe the next one or two towns, but certainly not all the way to Corcus for example and some of the guilds are bound to be that far and even further away from Magnolia.
