I envy you! I would say yes. 10 man raid content will be hard.. that depends on both your level of dedication, your skill at micro managing etc.. But two 5 boxers has so many other benefits. aside for 10 man content. Bottom line is, if you both are already boxing..more is always better, and 5 each is perfect right? Its why a single boxer almost always starts out "duel-boxing" and ends up at least boxing a full group later on, its the "power of more".
