__ Where we are right now:
With the upcoming patch, all the other farming trade skill aptitude chests like those for logging or harvesting have legendary items used to craft T5 items. Fishing chests will have baits. Yes, you read it right… baits!
Additionally to that, if you are just logging some wood for 1 hour and sell it for 0.10 each you make much more money than you would make with fishing for 1 hour (including traveling time to the different locations) at 3-star hotspots with fishing lvl 200 and full fishing luck set and fishing trophies. I am fishing level 200 and tested it on live. Fishing is not worth it right now. By far. Even if you would find a legendary fish now and then you could sell for 150 coins (which are again bound to certain region).
__ What can be done to make fishing more rewarding:
- For every successfully catched fish, give us x Azoth. Alternatively, give us some Azoth when we catch or open a treasure chest.
- Put some Firefly bait and Glowworm bait in Treasure Chests (even if its only 1 per kind). No bot would make money with that, but it will help the fishermen a bit with the hassle to get new baits if they would go out of baits in the middle of fishing.
- Give us territory standing points when we catch something. The better the catch, the more points we get.
- Put repair kits in the Treasure Chests so we can repair our stuff without paying money.
. Puit Bind On Pickup Azoth Vials in Treasure Chests. Or other useful items you just make BOP.
There are so many possibilities to make fishing more rewarding without giving the bots anything they could sell. I know you can come up with even better ideas, as you have professional game designers. I believe in you.
