These are quickly becoming one of my favorite things about guild wars 2 and they have so much potential to expand on.
Here is my suggestion. Include a few more mechanics in them. I’m thinking along the lines of Zelda style dungeons. You already include things such as placing rocks on pedestals to open gates but there are a lot of other things you can do as well.
For example burning cobwebs to open access to floors below you, obtaining keys from certain creatures in the jumping puzzle to open the proper gates, using explosives on certain walls to open access to the rest of the dungeon, hitting a switch to drain the lava from a room to obtain a key, etc.
I think there is already a trend for this however after one puzzle I did that made me use a land mine to blow myself across a pit so im really excited to see where in the future this leads to.
