in my opinion, travel Costs in the game should be reduced significantly. If you stay at a place for fishing, that's still ok. But if you want to change places often for fun, this is simply impossible due to the high travel costs. Therefore, you are forced to stay in one place longer before you "can" travel on. What I really think is a shame because of the many brilliant waters.
I also think that especially if you support the game with real money and buy an unlimited fishing license that should be recognized with low travel costs for this water/s.
