you have 2 choices to get the required gearscore to run the high end-game dungeons
1) you can spend millions or even billions of in-game gold to enhance/socket your gear
2) you can spend cash shop items to succeed all enchants/sockets in 1 go
reason I say millions or billions of in-game gold is because the best sockets have 1% chance of success~
bear in mind that there are many alternatives to acquiring cash shop currency, but in this day and age, ain't nobody got time for that~
that, and last time I played, PvP was a bit imbalanced...as well as slow release of new content. PW promised a new class, new race, and new instance/content with official release. So far they only released the new instance/content afaik.
the game also gets pretty grindy for end-game gear fast...dungeons have no variety~ and some bosses are either too hard or too easy.
