I would like to suggest a maximum amount of water that a hearthling can carry on him or add a movement debuff above a certain amount.
Currently anyone who pvp's just runs around with max amount of waterskins so he can keep running.
Since everyone is doing this, PVP is momentarily just a marathon contest.
Maybe by adding a maximum people will actually think up new tactics when engaging.
Make it so that you can only carry a max. of 15L? of water in your inventory at any given time without lowering your movement speed.
It doesn't make sense anyway that someone can carry 100L of water and still be able to run as fast as someone who has an empty inventory.
