A really simple thing we should start with is simply to place the dialog at the bottom of the page and move the skills up. That'll still make it long, but all relevant game information will be available up top.
Still, I'm pretty confident adding all follower dialog to one article will make it well over 100k big. It will be a lot of loading, perhaps having dedicated "dialog" page for followers and classes might be a good idea eventually? We could see how dialog develops once the game is released first though.
PlugY for Diablo II allows you to reset skills and stats, transfer items between characters in singleplayer, obtain all ladder runewords and do all Uberquests while offline. It is the only way to do all of the above. Please use it.
