Retainers, confirmed, you have to pay for them.

4$ for 2 a month + 15$ sup = 19$ a month

other P2P games don't cost as much as this and have same storage space or more.

I don't like this idea at all.

Or! since you only need 1 character. Cheap sub = $10, +$4 for retainers = $14 a month, still less than other p2p mmos.

Entry-level is $11.99, not 9.99. So you're paying $16 still, which is higher than most MMOs that offer more inventory storage options.

Why would you need 4 retainers?
700 item slots. A bit too much, isn't it?

Yeah, and also 8 character slots per server up to 40 in total (plus their inventories, armory, armoires, the two basic retainers, etc.) require more resources than two simple retainers.

2 simple retainer for each character slot. That would be 80 retainers total to be exactly.
Sure, nobody would create 40 characters and give every character 2 extra retainers, but the possibility is here.
