As the title says, the idea came to me while thinking about the eco of the market and the growing gap inbetween premuim and f2p players, prices are rising due to the influx of n-meseta from multiple sources some are legit and others are questionable and have caused quite a bit of contraversy.
I know this would reduce the "value" of premuim so to balance out the loss that would obviously cause arguments you can add the material storage to the premuim sub, while also having full shop, pso2 base perks, premuim pso2 day, more SA slots ect...
The reason i sugest the material storage is pretty simple, its value is second to none and already in the SG shop and anyone who has been playing pso2base or ngs will know the value in material storage, those that have premuim will normally have a monthly budget for material storage saved up to keep it active, if we add it to the premuim subscription the value of it in itself will be more than a 5-7 day shop pass.
This is just my idea to give access to the "open" market to F2P players and it works off the current systems in place and can be easily added, it will work just like how material storage does now and has been, we get SG through events and daily log ins, new players can go back to base and farm up 1000's of SG through the story and title system. So while it seems like giving f2p players free shop access, you still have to do some work and log in to obtain it and its not too bad to do once or twice a month.
If there is any better ideas or nitpicking so this can become a more well rounded idea, or if i have forgot an important factor, this idea can be changed and worked on with more input so (maybe) it can be implimented (if they read and listen) so it can be helpful while also minimizing the impact on other parts of this game.
