My worst problem (if I could call it that) is not so much failing to note the enemies range but more so when my units get hurt and I can't get Lissa or Maribelle (or my MU if she's a cleric/he's a priest) to them. I do mostly lose them during the enemies' turns and right after I healed someone else who had lower health than the unit that wasn't in any mortal danger of dying that dies usually when said unit had a full bar of health. Is there a way of determining who then would help to increase the chances of dual guards regardless of supports, or should I use maps like the Golden Gaffe/EXPonential Growth to try to level my units up as fast as I can? I already use the maps to help increase support points with some of my units (Chrom and the avatar come to mind here, or Frederick and Sumia or even Henry and Tharja).
Also you can't get javalins early into the game :) the best you can get is iron weaponry until after you complete side story 2 D: which is a struggle to get through unless I have MU at almost lv 10 or higher with the rest of the team at about 9-10 themselves. Higher leveled units I have found makes a good deal of difference :D
That aside I think I am very indecisive when it comes to who to pair with who. I know however that I like to have happy endings for the characters and tend to pair accordingly (although I have no idea how to pair child characters D: and am lost from the few I always pair up)
Thanks for the tips. I will definately keep them in mind for this current playthrough and when I get to the maMU playthrough!
Oh I forgot to add I didn't use Frederick all that much...I think it was because I didn't use him for that chapter and the team wasn't at a high enough level at the time.
