The excuse Jagex would give would be that "the difficulty of the skill is part of the game." What they really mean is "join members so you can gat fishing spots near banks." However, I am not Jagex and I am F2P and I agree with you. The only bank on all of Karamja is in Shilo Village and let's face it, That is one of the least accessable banks in the game. However, I think there should at least be a deposit box on Karamja or a messenger. The deposit box would be a bank but you couldn't withdraw from it. The messenger would take your items and deposit them and then bring back any items you need, For a price. I'm thinking it should be around 15-20 gold an item tell me what you think.
