While i like the idea of them, they do feel clunky because they only cast their ability when being in range, which makes sense but you also have to cast their ability in their range. So what if there would be a change to it that if you click the ability outside of their range, they would move into range and then fire instead of the game telling you that you cannot. This would also make managing groups more fun and consistant.

I understand that the reason for it is the fact that you need a building check for it to even work but if you destroy a building while the ability is ongoing, they stop their firing instandly so there is a permanent check on if a building is present which tells me that my suggestion would be possible.

not a terrible suggestion, something to keep an Eye, when going over a "glossing", the lesser thought out systems

This is not possible at the moment. Enabling this "Out of range" check is required when defining a minimum range.

But isn´t it the point? When the game sees that it is out of range, then they move towards the desired point until they are in range and then start firing. So even with minimum range you could have the same. Walk into the opposite direction until they are out of minimum range.
