As it is now, there's not really an endgame, nor is there any in sight because of the veteran ranks, which will (probably) be raised every time there's a new adventure zone. Doing this will make it so that the last adventure zone becomes useless to someone who has reached the VR requirement for that zone, and by that, all the content that will ever be developed will just be more levelling content instead of endgame.
Not that there's anything wrong with good levelling content, but I think having more good ACTUAL endgame content is important. Where you can really polish your gear instead of getting new gear.... forever... We're pretending there's an endgame by calling it Veteran Rank, but it's just more levelling. I call it; pretENDGAME (see what I did there?)
The Veteran Ranks are something that I think should be purely cosmetic or prestigious if you will. If this was the case, then we could keep the gear we worked so hard for on level 50 and actually have some use for it. Losing all my gear every time new content comes out is going to be pretty depressing I think.
But this is all just what I think of it, I'd like to see other opinions ^^
