To be fair, the treasure scenario is a GUARANTEED 15+ elder coins so there was no randomness to it (in fact if i leave there not capped at 20 when i start with 0, I had screwed up something, which is why i generously say 15). If you do the scenario correctly you always walk away with tons of coins. The comparison to timeless isle is that coins are too expensive by comparison. 15+ coins for 5 minutes of my time once a week, or 15 coins for like 10 hours of my time on timeless isle.
Please tell me where the magic button is, if I clear the the end, open 7-8 of the better chests I might!! get 8-12 coins. Heck half the time I pull a extra mob that pulls others and end up with 2-3 coins. Its not unusual to spend more coins on consumables for the run then I get out of the run.
I can not move that fast, I can not open chests that fast to get 15+.
