As sad as this sound it might actually be a possibility...
i'm all for bringing account wide versions of ex-promo items and cash shop only items, but not previous event items where only the character who did the event earned it. Or make it that everyone, who have the archievement on 1 character of the whole account get also the items for all the other characters without paying for it.
So NA people can just buy more things off amazon and EU people have to chase the single store close enough to them to reach in a day that sells whatever item SE picks out for them? Plus some people can afford cash shop items, but not the needless junk SE promotes. Or live somewhere where it's pretty much impossible to get any promotion campaign stuff. Yes cash shop, but a little less cash-grabby and more pay for what things are actually worth.
I'm fine with this.
For example, the "play dead" emote was never available from an in game event (AFAIK) and really is the sort of thing that should be available by default anyway.
It's currently the only option to make a character "lie down" when not on a bed while most other MMOs have a /liedown emote by default.
I just joined this game, and I would buy things from the store. I refuse until what I pay for applies to all account characters.
