It would be good if they gave all DK’s an ability which allowed them to create a temporary runeforge for a period of time that was on a certain cooldown timer (like 5 - 8 minutes).
The benefit of this is that a Deathknight would be able to change their Runeforge without having to Death Gate back to DK Class Hall, if you consider the fact that no other class really has to go back to their class hall for any relevant in game mechanism for Dragonflight. However, Deathknights who either need to put a Runeforge on a newly received weapon drop or change their Runeforge for certain mechanics etc. have to Death Gate out of their current location, change or put the runeforge on the weapon/s then Death Gate back.
Instead it would be much easier to have an ability which allows them to create a Runeforge at their current location that they can use to change or put runes on their weapons without having to go through the whole change of location etc. This would be very beneficial for things like PvP Area and being able to change your Runeforge in the preparation room based on enemy compositions. It could also be used in M+ Starting sections to change your Runeforge on a weapon and not have to carry multiple weapons with different runeforges depending on what is required.
It’s just a thought but having to go back to the DK Class Hall to change or put a Runeforge on can be annoying and a hindrance that other classes don’t have to deal with.
