Yes exactly! I had it wayyy worse when I first planned out the Dungeons and the fights only gave 1 Win Token per any win!
Now the Win Tokens work like this as of a long time ago: 1 Win Token if there are 2 enemies, 2 Tokens for 3 enemies, and 3 Tokens for 4 enemies. The same formula works for all of the dungeons (There is 1 dungeon per element) and then the Omni dungeon which is a little bit of everything and then a new dungeon im working on for the final area I have no idea what the rewards will be though!
Also the dungeons after the Rifthaven one allow you to buy higher tier seed bags :)
