Haven't played long enough to see this happen very often, and with arson coming out soon and seeing how items have switched category in preparation.
What other major items has this happened with?
Could this happen with weapon category items, flash grenades being used with OC 2.0 now comes to mind.
Has there been any weapons that have changed to tools, materials or enhancers?
Would be cool to see input from someone who's been around for a large part of torns history. It's really what I like most about torn is how deep it's history is and how it's begun to change with recent increases in player counts.
