I understand that the advance stat is for elemental builds and legion arms, but does it effect how quickly a boss or enemy becomes afflicted with a status like burn or acid? It feels like the flamethrower arm doesn't catch carcass enemies on fire as quickly as I feel it should, not sure if it's due to my low advance stat or if it's just the enemy's resistance. From my testing, they catch a status ailment faster if I use a special grinder and keep attacking vs using a legion arm to apply a status.

Since I was just using the legion arm for status buildup--and grinders work better at that--would It be better to just use the Falcon Eye arm with my technique build?
