Ill break it down for you:
Obviously things didnt go as planned, They are very well paid developers, they wernt just sitting on their *** doing nothing. Take a look at the patch notes, they put in work.
1) They push the patch out with rated wzs broken
result: community lashes out about ranked wzs being broken and exploited, free ranks given out, free gear earned for exploiting etc.
2)They hold back the patch.
result: community lashes out for the next 2 months about the patch being held back for ranked wzs.
3)Hold back ranked wz, push out patch
result: this.
all in all, its damage control. They are doing what they can, and like someone said in another thread (or this one, im posting a lot tonight) If you are playing swtor for pvp, you are playing the wrong game for pvp.
