it really says a lot to me how you describe the purpose of ARC training, it being made to train anyone and everyone who desired it. That was the original vision for ARC training and I love how you're putting a focus on it. As of now, as much as it hurts me to say, ARC really is the most outdated training by a long shot. After all, the beginning stages started in 2016, hardly anything else has remained the same since then. An overhaul is long overdue. It seems like you've put a lot of thought into this.
The ONLY thing that speaks out to me that I can't say I like is giving them the whitelist as an ARCT. I know I don't play anymore, but when I used to, the seeing someone on an ARC job during an event gave me two very useful consistent pieces of information (could make a huge difference in 1-lifes or large events). 1.) I know that they'll have similar firepower to me, I know their equipment. 2.) I know we will at least be somewhat on the same page assuming they remember the training, lets me know there are more communication options available. Allowing trainees will kinda ruin the second benefit, but like I said, unless it's a one-life event or something where I'm separated and looking for backup, it won't really change a lot. It's more of a comfort thing.
+1 honestly dude no way to know if it'll work without trying. GOOD LUCK!!! If it ends up sucking, you can just revert back no big deal
