The three passive weapons Mine, Mystic Mine and FlameGate must be re-arm after triggered during an attack. All three kinds need as unit to re-arm / refill Gold This is at the first sight logical, because weapons must be paid with Gold. But is this the best solution? Overview ressources Gold founding perk recruiting special pirate like CS buying in market upgrading Grog founding perk recruitment training buying market upgrading BP founding perk buying in market upgrading EP founding perk buying in market upgrading Summary It is needed much more Gold as Grog for buying in market and upgrading The Grog costs for training are high but a player must more and can faster upgrade as he/she can train his/ her troops. The Grog for recruitment is often free because many player plunder for Gold and Grog is bycatch. That's why in my opinion players have often more Grog as Gold. Overthink Gold as unit for re-arm / re-fill How could a player spend less Gold but more Grog? Mine Gold because Mine was paid in Gold like all other weapons. Maybe rethinking cost per re-arm. 65 K Gold for one level 4 Mine is very high (5 Mines = 325 K Gold) Mystic Mine Grog because Mystic Mine was paid in Gold but compared with the other waepons a Mystic Mine does not harm a pirate. The pirate fall just a sleep for seconds like after to much Grog FlameGate Grog because Grog is liquid and burn, Gold not If Midoki offer in near future (the next updates) new opportunities to spend Gold and Grog a change could be unnessesary Masterlist @Bear
