Don't know if anyone mentioned, but should they increase the stack size? I think 10x of these is pretty small for stack and taking huge amount of space in inventory. Inventory is aleready mess and full now as it is. And no I do not want to use them yet, I will wait for atleast 100% pvp xp boost before using them, or if they ever add new pvp levels I use them then, but right now having hundreds of those on my sin and no where to put them ^^
