The same as every other medium player. How to get enough sps for vouchers to buy 1k to 2k packs?
Im hoping that at $4 some of the larger accounts would rather sell than whale in again but that might just be wishful thinking. They will probably do the exact same again.
I can't see selling vouchers being that popular! If they go for less than $3 a pop I'll be amazed.
A voucher is only worth getting in on the presale and to most small accounts that is nothing. I think you will pick them up for less than a dollar as the days wear on. Not many people will be willing to pay big just to get in a small bit earlier. Unless the perks are very good.
