Umm ; no.

Having played WAR for 2 months, I have seen the end-game.

Heck : one of their bragging points is that you experiencing 'end-game' from T2 onwards !

A handful of sequential visually-indistuinguishable ( currently badly statted ) armor sets to aim for plus 80 Renown Ranks with astronomically escalating requirements - and similarly scaling RR purchase requirements - is not great depth.

Your character has all the abilities they will ever - and 99% of the power they will ever have - have when you hit rank 40 ( even by 30 you can acquire the highest Mastery abilities )... with zero fluff content, after that player satisfaction is entirely dependant on individual propensity for 'realm pride' spirit.

It is VERY cool the first time you are in a 100-player open RvR army / mob, but once you have been through both sides of a T4 siege there aren't really many variations to be had - door, fight, door, fight > win or lose.

I was also among those unhappy few to battle in the capitals during beta, and they just ain't the greatest PQs - even overlooking that capital rank has negligible impact on anyone but city dungeon farming guilds.

There is a whole lot of traffic through T1-3 that says people ( like me ) are reaching 'the end' and finding the most appealing option is simply to start again... Mythic are playing to these fans well by adding / restoring careers as major updates, but this cannot go on forever ( both the adding of careers and enthusiasm for replaying ).

End-game needs SOMETHING more tangible to hook people for the long haul, and Mythic have fenced themselves in to a corner in this regard by eliminating power, visuals, property ownership and crafting progression.
