Lol at Azir soloing Ishgal. Natsu alone is enough for him. xDD

If God Serena is not Yury and not one of the strongest Spriggans, then Laxus probably won't fight him. I wonder how strong the remaining Spriggans are though...

So the way I see it, the match-ups so far are:
 * 1) Laxus vs. God Serena (if he's Yury) / August (if he's not)
 * 2) Erza vs. Brandish / Dimaria (or both. Who knows really..)
 * 3) Natsu vs. Azir (and Zeref)
 * 4) Gray vs. Imber (Imber's the Ice Dragon Slayer. Calling it now).

Btw, I don't see the other guilds in Ishgal helping in fights against the Spriggans (Sabertooth, Lamia Scale etc) because they haven't improved as much as the core members of FT have (being busy with jobs, vacations and all that..). The most they can do imo is sort the "730 guilds" problem. The main members of FT, 10 Wizard Saints and CS should be enough to deal with the shields tbh.
