Wires cannot be Ctrl + dragged off reroute nodes. Ctrl + clicking and dragging the wire from a pin on other nodes acts the same as Ctrl + click-dragging from the pin itself, but on Reroute nodes this option isn't available.
Reproduced in 4.8 Preview 2 and Main (//depot/UE4/Promotable-CL-2554325)
1. Open any project
2. Open any Blueprint
3. Event Begin Play > Reroute Node > Print String
4. Ctrl + Drag the wire near the reroute node from either side
The wire does not separate from the node as it would from any other type of node.
