It's actually very simple. For a technical explanation, we go to Crux/Lomar Engineer Bob Sajak. Bob, take it away: "Thank you. The Truth alteration was proposed for a very good reason. Propulsion of Truth rockets is a little different from most rocket launchers. In addition to powdered aluminum and an ammonium perchlorate oxidizer, Truth rockets with their aggressive tracking have an additional polybutadiene acetonitrile burst, that'll cause a transient vapour cloud that unfortunately persists for about two seconds. The result is a slight toxicity risk to users that adversely affects your nervous system exponentially with the local concentration of vapour around your head." "Now at first we thought it was no problem, given that you're firing your rockets while wearing a helmet- however, long term studies, over two and a half years, showed that when the vapour cloud reaches a certain concentration, the condensed residue will linger and adhere to that helmet- meaning when you take it off, handle it, are around other people not wearing helmets, well let's say there's a significant toxicity burden." "If you simply space out shots, allowing at least a couple of seconds in-between firings, then you remove this risk. So you can see that reducing the mag size in Truth rocket launchers is a safety precaution that simply had to be implemented." Thank you Bob, for the detailed explanation. Hopefully this clears things up, and puts the minds of our Guardians at ease. Now about those health regen nerfs.......
