The weekly cap on Classic Commendations will be removed in an upcoming patch.
Incidentally, there is currently a bug that causes the game to warn you that you've exceeded your weekly cap even when you are at 0 in your weekly progress (it's erroneously looking at your total commendations). Make sure you check the actual weekly progress value displayed in your currency tab.
I personally think all the weekly caps need to go away....at least for subs anyway. This is not a good system for subscribers; however, it is a neat little way to possibly milk a little more cash out of F2Ps.
