As you are well aware, applying Meta-magic feats can have some weird effects if you multiclass spellcasting characters. As Xavier once explained, it is linked with the alphabetical order of the class name: http://www.co8.org/forum/showpost.php?p=114030&postcount=9 Now - this might sound like a bit of a silly (and I fear impossible because of hardcoded) suggestion- but is it possible to otherwise change the names of the classes? A Wizard could become a Mage and a Sorceror could become an Aetherwitch, for instance. I know that it would make things a bit difficult plus it would deviate from the d&d rules, but I really once would like to play with a Mage/Ranger who's able to use metamagic feats on his more potent spells
