As things are at the moment, there’s little incentive for a player to redo a dungeon in story mode, since they would be getting zero tokens for their effort. That means first timers have a hard time finding someone to tag along for story mode (I’ve witnessed this problem a lot in my guild). So my suggestion is that story mode should also reward tokens, albeit probably less than in explorer mode. Let’s say 20 tokens, which is the same you’d get for repeating a path in explorable mode.
