OP I see why you're having mana issues. You spam high mana spells inappropriately, have tunnel vision wanting to do the most damaging abilities and don't want to stop doing damage so you come to the forums hoping that developers make Summoners into the gods of spellcasting where you'll never have to manage resources ever.

LOL! managing resources is a part of the game, even BLM's have to deal with it. How much DPS do you think they lose when they switch over to Blizzard? They HAVE to, to get their mana back. Just like WE have to use Energy Drain in order to get back ours. If you're still doing the wrong rotations (I blame it on forums really b/c I've NEVER had a problem) and you're not using ED like you're supposed to then that's on you.
