All other towers, ie; Pitfall Trap reduces attacking Infantry by 50%, Barricade reduces 50% of Calvery etc. The Ballista Tower offers no such reduction in attacking forces.  All towers will allow the use of city guard troops.  So why leave out this feature on this tower?

I rewrote the Dungeons wiki.  Please provide any feedback, including errors, omissions, issues regarding conciseness, etc.
