For those of you complaining that "those other MMOs have way more space", a moment of consideration.

1) You end up paying for that extra space in almost every MMO I've ever played -- on a per-character basis.

2) If Wow had a 40 slot bag, there would be 4 x 40 = 160 + 16 = 176 slots on your personal inventory and a maximum of 7 x 40 = 280 slots for stuff and another 100 slots for materials [around 550 slots] I can tell you from experience that most players never use use those 100 slots for mats, and, after Transmog no longer required a bag slot, those 280 bank slots are pretty empty these days.

We get 2 x 175 slots for retainers = 350 and (memory lapse here), about 150 slots for personal inventory. [around 500 slots]



Rather than ask for an extra retainer, you should be asking for (1) stacking of materials greater than 99 and/or (2) a glamour log so you can get rid of all that gear.

SE knows how many people fork over the cash for extra retainers. If it is 5% of the playerbase, why add another retainer in-game that isn't going to be used? If it is 45-60% of the playerbase I suspect they'd consider it.
