Summary Add a "Rune Exchange Shop" tab in the Trader to exchange Runes for other Runes. Description Upgrade the Trader with an "Rune Exchange Shop". The Shop will give the possibility to change a Rune into an other Rune by paying an "Exchange Fee". The Runes are offered by Players or the Trader (Inside a Fellowship: Half the Fee). This Shop is only visible if both sides have upgraded the Trader. The Shop also gives you the possibility to SELL a Rune (maybe for defined prize). It is not possible to BUY a Rune, that's to easy to get one. Motivation With all the new AWs coming up, it's getting harder and harder to get the Runes you want. Furthermore this would make Runes of already built AWs more valuable. It would enhance the usage of the AW feature in the game. Possible downsides We shouldn't make it too easy to obtain certain Runes, to keep the game challenging enough.
