I'm almost certain I've ticketed this before, but it's a bit more apparent as an issue now.
The display currently has WMDX as a tag. Ideally, this should instead read "X% to hardened targets". This gives the actual WMD damage value, rather than the rating. It also ensures currect display of WMD damage for WMD0 rated weapons in 1.7a1 and above. This could be done in brackets after the "blah damage at blah per second" section, on the same line, rather than using a tag (which would be too cramped for the full text)
