My suggestion is Location Potions.. wouldn't it be wonderful if we had to do less running and give out less kamas to each and every Zaap?
The idea isn't to cut out the zaap system, if anything it's one of the things i love about both Dofus and Wakfu. The idea however is to implement a similar idea as Dofus, there they have potions to get from point A to point B yet still use zaaps allot.
Let me explain in a tad more detail, at the moment we use the zaaps to go just about everywhere and 2 kamas per trip don't seem like much at first yet at times we don't really keep track with our traveling tendencies so after a while that 2 kama trip ends up being about 20 kamas at the end of the day. Location potions should be craftable, to make it harder to get hold of and a bit more work to get, the point would be to have a Bonta, Brakmar, Amakna, Sufokia and Asturb potion.
A potion for each main city so it's easy to travel between cities, yet zaaps still have their purpose when it comes to Islands and if you lack potions or simply cant be bothered still have the option to zaap travel. Of course the potion would only take you to each nations headquarters making it necessary to still travel by other means as well.
