Apologies if this double posts. The Escapist site has become so slow since this update that posts are getting shot straight into the aether.
I played Warhammer for a good 8 months; so, I lasted longer than most. The things that killed that game were the major gameplay bugs, the broken class balance(which turned into a faction balance issue because of the way the classes between the factions were designed), the lacking end-game, and the sparse population(the game opened with far too many servers, and players were being too thinly distributed among them). There were a lot of great ideas in the game(many of which WoW has since incorporated), but the implementation just failed to allow those ideas to really shine in a cohesive manner.
The PvP in the game was great at the outset, but eventually it became tedious and lacking in motivation. Coupled with the issues of class/faction balance, it could get absolutely frustrating at times. Also, thanks to the very low population on the servers, often times PvP would devolve into what we called "PvDoor". The keep doors took forever to knock down, especially in the early days of the game, and were a serious bottleneck to getting into a keep to attempt to capture it(I discovered a combination of skills on my sorceress that allowed me to cast infinite Pit of Shades with a high crit percentage, like 90%, and almost single-handedly defend a keep because no one could stand at the door long enough to damage it before they died; siege engines did not last long against my Pits). More than 80% of your effort went into just get through the door.
Nowadays, I think most people just play the perpetual free-trial and just fight in the tier 1 battle areas. There are still a number of veterans in the tier 4, but they're so powerful now, a newbie has almost no hope at all against them. You would probably have to grind up to renown rank 70 before setting foot into tier 4 to have any chance against them; otherwise, you'll do be hitting them for like 1-5% of their life on each hit, while they just 1 and 2-shot you.
