The Key is Balance, Anet
yes, balance is important, but player population is important too.
new, improved rewards will attract more players.
but if the bucket has a big hole (balance issues) in it, no matter how much water (new players) we pour into the bucket, water will keep flowing out also.
even if they patch up the big hole (balance issues) in the bucket, but there is no one pouring water (rewards) into the bucket, the bucket will still be empty.
fix the balance.
improve the rewards.
convert those PvE / WvW players!
