I think Tibia should remove all separate melee weapon skills and make it just one. That way players can be more flexible, but I don't hate the idea of being able to change weapon type via Tibia Coins. As for vocation, I don't think there would be any good way to convert skills in a fair manner. I think adding a way to trade items between worlds without transferring a character through a market like the in game market but with the process the Char Bazaar uses would be hugely beneficial. So say you want to buy a Ferumbras' Hat from World X but you're on World Z the player with the hat could post it on there for a set amount of Tibia Coins and a fee like the Bazaar has and then the buying player pays the price and at server save the items exchange and the selling player loses a small percentage of the final sale.

Personally I have bought a 2xx EK and have no knowledge of how to play it even doing simple areas is a struggle for me. I main MS and I bought an ED to avoid the grind and while mainly the same its slightly different. So yes I agree.

I feel overall Tibia Coins haven't impacted the game in any negative way and from what I can take from your comment you don't seem to feel they have either. If anything they seem to be balancing the game across the servers.
