All the current system does is make you wait one extra week. The current process is:
1) Level to 19 in whatever, take your last level in the class you want to be
2) Use an LR+5
3) Wait 1 week
4) Use an LR+5
Ready to TR
Basically you are just creating a 1 week delay.
If the person only had LR+3s available, then you would be adding a 2 week delay, or forcing them to only go to 15 or 16 in their favored class, no big loss.
So taking out a 1 or 2 week delay before TR is "pay2win"? I'm not seeing it. You aren't making the game any easier to play, you are just taking out an artificial delay that doesn't really change much.
