As a player who tends to play mostly early in the morning, patch 1.1.0a introduced a frustrating problem for me. This morning I logged in at about 6am, as I often do. I queued myself for a WZ and then headed to Ilum to attempt to do the daily.
The republic population on Ilum was 4, and none of the other 3 were doing PvP. I decided to see if I could farm armaments and pick up a few random open world kills. Unfortunately, since the armaments are concentrated only at the central assault, and since there were about 15 imperials there, this proved to be impossible.
Oh well, at least I can do Warzones which are balanced. If only that were the case!
I then proceeded to wait in a queue for approximately one hour for my queue to pop (it didn't). The fact is that on my server, there just aren't enough level 50's to support PvPing in anything but peak hours. Prior to the separation of brackets, this worked fine. This makes me think the split was TOO SOON. I'm all for splitting the brackets up, but they should have waited until enough people were at level 50 for the ecosystem to be viable.
The bottom line is that prior to 1.1.0, I could participate in Ilum and Warzones during my odd play schedule, and now I simply cannot. It wasn't ideal before, but at least it was possible.
