You don't agree? Just don't make offers. That's simple. Why bothering complaining, this will not change facts.
Please notice I sold thousand of SS 750/700 each. Why? Don't know, is market and market is based upon need and offer and, in the case of SS, that market is the only almost player driven (God bless the game designer). Probably the more TC activity of many faction boosted SS price and probably less players are crafting them. I do.
Want to lower that? Just stop idling in Hub, gather resources and craft them. Is not fun at all, better enter in other encounters and kill players, or getting fun on WH/Reno and TC. I love to spend my game time crafting and sell SS and lvl Book.
