I've commented this in another area, but alongside the technical side of putting in a grand exchange tax, I think it needs a little bit of lore to make it feel like a useful part of the game. Who, after all, do you think is behind this?
The grand exchange is a trading octogon with a direct rail connection to Keldagrim and the 8 companies of the consortium... coincidence? I think not!
I think the Dwarves have given their 'free trial' of the new Grand Exchange service quite enough time, that now they can start to actually charge fees. Alongside a 2% markup (a generous rate) they could even charge adventurers a security fee for using their complex (which they've had to build half of gielinor away!) for the day.
If it's good enough for the rulers of Al Kharid to charge entry, it's good enough for the consortium of Keldagrim.
Could you imagine the treasury that starts to accumulate in Keldagrim? The dwarves have to spend that gold on something you know. The more rare items that are 'bought' out of the game, the more we seem them appear locked away in their treasury
just
safely out of reach of being tele-grabbed.
I wouldn't be surprised either if this leads to more interesting drama (and quests?) centred on Keldagrim. And the trainline that connects the markets of Keldagrim, the Grand Exchange, and Dorgesh Kaan.
And if you don't like the tax...
cough
... I mean Grand Exchange fee; the dwarves are more than happy to direct you to trade directly with other players without using their services.
Kind of gives a bit of lore and 'fun' to the Grand Exchange, and a slight nudge to encourage players to trade person to person again. Which I think is an important part of an mmorpg.
