This ability would be nice mainly for WvW. While attacking a gate or wall most people will put up more than one ram. Once one of the rams are built it can sometime be difficult to change the F action from use to build. I find my self moving my character all over the place inorder to change the F action.
The F action priority was a nice addition but the use action is natualy of a higher priority than the build action. So I was thinking of a simple fix to this problem like implementing the > key as a toggle that way I can get in build and get away before AOE kills me.
