@Furasian since you want to keep track of whos on what side I'll restate my point of view. (also maybe just make a vote instead of getting a bunch of long winded opinions like this one)
Credentials...I'm a sec main with over 800 hours of playtime, at least 700 of that being in sec. Probably more than most. I've seen several generations of security players come and go.
This job is already handled by veteran security players when they have the time and are available and just by simply playing and learning the hard way. Someone can talk to you for hours about how to be security, you'll still never learn as much as you do through simply putting hours in and experiencing the endless scenarios being security throws at you. If someone cannot handle learning through failing and dying countless times then honestly security isnt the right job for them anyways. Security has functioned perfectly fine for years without this field training officer existing.
I also have played long enough to know that it is perfectly fine that security is not effective all the time. It makes security and the server more interesting when the the effectiveness of security fluctuates. Sometimes its a well oiled machine, sometimes its a hot mess, and everything in between. All of those are acceptable.
I truly don't beleive adding this role will actually have a noticable effect on anything. Everyone will still learn the same way they always have. I know people are just gonna stick with thier guns but I think any effort put into creating this role or even discussing it has been a waste of time. Including this post from me.
