How does the NL market change when ladder season ends?

Hey all,

With the ladder season coming to a close soon, I've been wondering: what does this do to the NL market? Perhaps nothing, but does this change the relative supply and demand of certain items? I haven't been around long enough to know, and I've been curious about it.

Of course, the ladder only stuff coming to NL changes that supply drastically, but I'm more so wondering for the non ladder only items.

Any random thoughts/insights would be appreciated

There is a massive ladder only runewords sale and the prices of the others items keeps increasing.
This leads to a general devaluation of market values.

After 12 seasons, the value of a

Jah rune is almost the price of an

Ist rune after 2 or 3 seasons.
So almost only perfect items are valuable.
