I get the impression that EO3 is a lot more open with viable party strategies, especially with the subclassing adding another layer to that. I made what turned out to be the "default" party in EO1 and 2 completely by accident (EO2 in particular, I stumbled across and cobbled together RDW/HG after my first team didn't work out, only to find out later that that was what absolutely everyone ran) so it would be pretty refreshing if I put forward my build and got met with "huh, that's interesting, well more power to you if it works :D" rather than "oh God, another Prince/Hoplite/Monk//Arbalest/Farmer team?" (From what I've seen, it appears that a lot of people like the Ninja/Zodiac Free Dark Ether For Everyone trick, but I haven't really seen a clear consensus beyond that.)
