I can only speak for myself, but my bot margins are lower now than before the patch (yes there's the whole discussion of what the price of 'stocked' goods should be, but leave that for another thread as that's really just matter of transition). So what creates high prices is not uncertainty, but rather high raw materials prices. Almost all except noralgis I'd say will fall for sure. However, for the t4 and high end bots, noralgis is pretty much the only thing that matters.Will noralgis fall? That's a hard question. Demand will increase at least 10x compared to pre-patch and yields have been reduced. Perhaps massive plantations on gamma can counteract that, but saying that they'll for sure fall is nothing but wild, wild speculation at this point.
Just to illustrate my point on this, if ALL raw materials fall in price by 30% compared to pre-patch level while noralgis keeps constant, then the prices of the following bots will change as follows:
Riveler: -6%
Mesmer: -11%
Vagabond: -17%
Kain: -15%
So yes, some price drops may be on the horizon if base ores fall (as they probably will to some extent at least), but don't expect too large drops unless noralgis starts going cheap!
