Yeah well you can work around the bag issues yourself. Buying lots of green and red bags and stick them into the bank (they are small and exclusive...). However, there is no orange bag you can buy for plat and I've thrown away all the favor ones except one for each char, since I thought I'll never need them (I just dump stuff into crafting bank after a round of legendary quests)
But I think players should not have to grind or pay DP (for bigger bags, another mule to store all the ingredients that didn't fit) to sort that out.
It is possible to work server merge problems out, so I hope they merge servers before it is too late and too many people quit over low population.
