We were talking about people/dynasties, see original post. Diadochi and Epigoni both have other uses. To most its just all Diadochi, but I've been confronted with the term epigoni (and with the greek thing I just meant that however the greeks called them, we still call them diadochi and epigoni). All I did was pointing out the difference and I'm really having enough of this, if you feel the need to go deeper into this I suggest you guys come to Belgium and give this whole tirade to my professor, he might have to rewrite his whole course ...
edit: I hope that in the future you keep the compliments to yourself, well it was nice to be "nitpicking" and "arrogant" with you guys
