If you don't have any arena points then emblems may be the best option. I have about 2000 spare arena points however and have everything I want so far. I remember that last season the week before the change however they reduced the requirements for gear so that they became purchaseable. Considering that arena points will be wiped, I will be sure to cash them in on anything I can before the season ends, but I will wait untl that last week to see if any bargains come up again.
