I LOVE vendor search both as a merchant AND as a shopper - omg it has made my life SO much easier! I no longer have the sheer drudgery of going around dropping runes, and I'm selling stuff just fine (way out in the boonies, not even in Luna or Tok!!) as the search allows me to price my stuff competitively and quickly!
As for the ec v 2d argument, omg give me a break! After all these yrs? Seriously? Look I use 2d, i have tried using ec - multiple times, but I dont like most of the graphics (paperdoll is an exception, lol) I dont like the movement and I dont like the color scheme - I just prefer 2d and that's what I'm going to use. Nor am I going to waste time complaining about which client peeps use, it's a personal choice and that's that. I know many, many peeps who have lots of gold to spend, like to shop, and also only use 2d.
SO.. that said, ec users who want to ACTUALLY sell things to 2d users need to accept the fact that folks using 2d simply cannot see all the items you have for sale if you don't bother to stock the vendor in your legacy view. If we cant get at the item to even click 'buy' - we can't buy it. Seems pretty darn straight-forward to me.
And stating that 'well you should all use ec' is a ridiculous and very unhelpful comment.
Ok that's my two bits, lol
