Sure. If they can add it without giving every player the option to have any scroll in the shop indefinitely
No point when u can watch videos on youtube. There's a reason why we have previews for scrolls and exos. Nothing is free in game besides events. Lately everything else has been a gamble and grind. Might as watch the previews and pay for what u want.
or more likely option: nimonix keep adding 1 day rental scrolls to medal shop, that's pretty much the closest thing we got to a "test scroll" option might as well do more with it
