Why is that Gildarts not too involved in guild fights? There are so many situations where the Fairy-tail guild gets into really tough fights and in serious trouble!. Gildarts is extremely strong, how is that he is not very involved in fights??
As said before Gildarts is a class S mage and he is almost always adventuring. For example there was an episode when Gildarts came to the Guild and everyone was doing a party.(I don´t remember in which episode it happened thought). Even if he wanted to join the fight´s he would need some "days" to reach the "battlefield".
