I am not really a big spender so I usually do Royal Jelly runs on tier 2 or just do any ordinary road. I think there should be new bosses with new roads towards them. Tier 1 should at least get 1, tier 2 should have 2, tier 3.. haven't been there but I think 2 is enough.
Now who is with me!!!!!
I know the game is just new and maybe their even making them now, but you never know so shout out if you agree!!!
Honestly, every road should end in at least some kind of mini-boss with a small treasure vault after him like the Jelly.
Maybe not something as rewarding as the Royal Jelly, at least not in Tier 2, but just something to make going down non-boss dungeons worthwhile.
