http://imgur.com/a/XmRTf Spoiler: Pictchas Noticed the error when messing with my SP on my Launcher - the actual damage numbers for FM-92 Stinger SW went down, rather than up, between ranks 1 and 2. I assumed this was a visual bug and went to test on the Reinforcement Machine. In both tests I had +90 STR from my Hand Cannon and 1 stack of Heavy Weapon Mastery active. There was no change to anything in my build or equipment setup except for Rank 1 or Rank 2 of FM-92 Stinger SW (EX Stinger). It's plainly obvious on both Critical and non-Critical damage that Rank 1 of the skill did noticeably more damage. I'm reporting this to Neople, but in the meantime I highly recommend leaving the skill at Rank 1. I don't have the means to test whether the trend continues at Rank 3 or whether it reverts to "correct" values or whether this impacts F-Launchers.
