The amount of 6 boxers I saw inflates it for sure. But seems pretty decent. The story will be 2 months in and you still got 2.5 months to go of velious. Hell I figure you could log in that 4th month of velious, find some extremely cheap raid gear and then go to town right from level 1 with it(since no required levels on gear, just recc) and easily be ready for luclin in those 2 weeks. Same with luclin to pop(avoiding VT).
The real picture will come to see if it last post PoP, when most seem to quit and when the server really kicks off imo(8 weeks for everything, more expansions tied together like dodh/por). A lot of that depends on their 2027 offering(as I dont expect to the TSS start one to garner too many) and if any other big games kick off(say gta6). Also if that legends things actually becomes something, hard to tell based off this forum with so many hating it just because who is helping develop it.
