However, I'll say it straight – I like to use "the full package," meaning to utilize all the resources and ideas of the game to the fullest extent.
Favorite heroes, dynasty weapons, unique heroes (including their appearance), special ability slots – all of these add interest to the game.
Besides, what's the point of paying for all of this if you're not going to use it? (Pirates, of course, have a problem in this regard; they are forced to play a cut-down version – but it's their own fault, and they get it for free.)
