The thing is that all the features that i am thinking about where there when other older MMOs launched like Lineage2. Territories that could be controlled by conquering the castle of the area, an Olympiad system that had fair 1v1 matches in a colliseum and every month a new hero, huge raids that needed 50 players to take down and above all a crafting sytem with 6 tiers and up to 10 sets per tier starting from Lvl 1.
THESE WERE ALL IN THE BEGINNING OF A GAME 10 YEARS AGO!!!!!!!!!!!
Yet the features i am thinking about were from other MMO's you haven't mentioned yet i played. Do you realise that at one time, and this was for a very long period, years before Cross-Realm was introduced in Wow, the minimum wait time for Alterac Valley was around 50 mins. At times you could be still waiting for 2 hours. Arenas were not there from day one either. The way rewards were implemented back then was terrible, where you could be stuck at one rank for months without access to any further gear, of which there wasn't a great deal to speak of either.
