That could be interesting. It all really depends on what they keep and what they change. Will they be dropping all expansion packs and all that has come along with them? What would happen when new xpacs come out? Will they keep battlegrounds in or after 3 weeks of launch if you're not 50 don't bother going to the frontier for RvR or XP? Will they remove all of the enhancements for cap increases and swing/cast speed etc... When the classic servers came out and people couldn't cap those as easily many players left the servers because they wanted the bigger/better/faster etc... People think back to the old days and going out to the frontier for XP groups. That will never happen, even on these servers, the old camps are well known and will be patrolled by other realms looking for rps. The old keeps had serious flaws to them, will enchanters be able to PBAE through walls and gates again? Will archers be able to volley through the roofs again? Running to emain did stink, and unless you were in a regular group you were screwed.
Nostalgia clouds the vision of many people. I loved the old frontiers and knew them like the back of my hand. I knew where to find lowbies xping and i knew where to go for xp that I would never be found, unless someone was using radar. I hated getting stuck in lame standoffs at the mile gates, casters of course loved those. Some of my most memorable fights were in old frontiers, it was almost set up for small groups, new frontiers is so large and much of it is empty that finding a fight other than the zerg or a keep is hard. I hate with a passion how the RW map shows any and every fight on it.
It would indeed be very interesting to see this server. However, I cannot get overly excited about it until I see more details. What about the epic quests will they go back to the old format and the old armour stats/design? If you really think about it for a while there are so many questions about how this server would be implemented.
