Ghost, Arena Point cap is incredibly flawed

I posted regarding this topic on the Customer Service forums first for clarification:

Now that the higher rated players have started to reach over 4k arena points, and assuming they want to buy a 4500 arena point item, did Blizzard honestly not foresee almost every single player wishing to buy one of these to go over the 5000 point cap?

In my situation, I'll have well over 1200 points earned next week and I'm already at 4346 points right now after the update. If I wanted to buy a 4500 point item, that would force me to waste over 500 arena points for absolutely nothing. How does this make sense?

Please hotfix this issue before it becomes even more problematic next week when people actually begin hitting this cap and lose points because of it.

If you're a player this could possibly affect, please bump this thread until it is resolved.
