So my main team at the moment is Cecil, Kain, Rydia, Kuja, and Bartz. I'm wrecking face through the story (early) and I'm enjoying it. This is the first "mobile" game I'm really not feeling the urge to get the most OP units ever and build the most efficient cookie cutter team. I think that says a lot about the game, or my FFIV nostalgia. Either way I'm having a blast. I lead with Cecil and my ID's in the spreadsheet, feel free to add me, just note GAF so I can make room for you fine folks.
At what point am I going to run into problems with this team? Just the occasional special dungeon? If so I'm not going to worry too much about it, if I'll actually run into issues in the story then I'm going to be concerned.
