1) The only way I think you can do this is to re-arrange your party beforehand, setting the character you want to move first in the #1 position and so-on. You can't change it up mid-map, and I think PvP also has its own timing (maybe based on character power level?). 2) You can move and attack, but not attack and move. Using a basic attack or skill will automatically end your turn. 3) It's just the blue bar on a map to my knowledge, which doesn't make much sense now that I think about it. You can see the total MP stats of your characters out of battle though. This a really good SRPG for an F2P - haven't really seen a paywall, more important than anything though is to just manage the free crystals the game gives you wisely. I didn't do this and I'm kicking myself now cause I have these more or less obsolete 1* sets/uniques but yeah. Live and learn I guess. From what I hear, crystals should go into A) leveling expedition to Lv. 4 to launch more than one at once, and B) a costume for your hero (the Black Magician one is apparently the best). People also say adding friend slots is good for more hearts. Just read over the post above me and it looks like they're making it a bit easier to get your characters too, which is fantastic. IGN is Elunix, feel free to add me though admittedly I don't have many spots left at the moment. My highest is a 2* Kai at 36, though I have my Carrot as my Mercenary just cause I think she's a bit more useful in a backup situation.
