Offering a lower-tier AI and making users pay for a subscription for a core game experience that is higher-tier blatantly goes against what has propelled AI Dungeon to become quite popular; ease of use and freedom. Additional features such as narration and certain paramaters are ultimately less consequential to lock behind a paywall, and do not take away from the core experience. The move puts off those who enjoy the AI but cannot spare the money to pay for Dragon, especially now when the finances of many are strained due to the pandemic.
Please, make Dragon free for all to use.
