I just hung on because I loved Star Wars.
Unfortunately, SWTOR is despite how we choose to describe it, a business... That's it, plain, and simple.
It's gonna cost way too much to implement the "wishlist" for those of us left. Cross server- pvp, world pvp, class balances, ranked warzones, more warzone maps, bug fixes etc all cost money and lots of it.
Simple answer, the staff probably want to fix it, but the board of directors, shareholders etc just won't allocate the funding. Why? Cause its a business and the number one aim in any business is ... profit
See you guys in the "new game"
