Pleaseee yes lol. Also add it to the shown skills when in use so that we have an idea of when it'll expire?
Thinking about this further, if the skill did have an indicator icon in the top right, this could enable the user to remove the door by right clicking. This would resolve some frustration for those times in which there are 2 bishops that have cast overlapping doors to different locations.
I like the idea too About the skill show icon , there was a discussion about it and its a no, i dont remember its impossible or they dont want to change it
