Feeble, I see where your coming from. This is pretaining to you sig. From what I heard the losses are:

Chrit - A respected battler, and great mod
13th Disiple - Also a very good battler
C-Section - He modded his forums well, but was mostly know for his witty comments
The Realist - Also a good mod, but very new to the site

While there may not be people who can fill those exact roles members have to start filling up the gap left by those.
