This patch alters rNameplates to shorten names differently. See the screenshot for an example. In raids and dungeons mobs regularly have longer names than the nameplates will display and are shortened with an ellipsis chopping off the last word. In most cases the most important part of the mob's name is the last word.
To install just unpack the zip into your addon folder and when prompted to overwrite core.lua do so.
Credit to Zork for rNameplates and all the work he does for the addon community. I believe I originally got the code snippet used from Tekkub in a forum post a long time ago. It's reworked a bit but credit to them as well.
