Getting back on R6 after ~2ish years

Hello guys, excuse my bad english as it's not my first language. Also sorry if this kind of post is not allowed, I'm not used to reddit and I'm kinda desperate.

My friends and I plan on getting back on r6 and I wanna know what changes should I know, specially about the operators I used more. For example Maestro has 3 cams now and I didn't know that until I saw it on a TikTok lmao. Other change I remember was Valk cam's being slower. Is there any video that addresses this? The only ones I've found only talk about the new operator for each season and changes like some ops getting acog's and stuff but not the ones I'm looking for.

If there isn't a video like the one I'm looking for, then I'd be very thankful if someone is kind enough to let me know on the comments or PM🙏

I'd list my mains but I use a lot of operators as I choose depending on the team, site, etc. So if you know about the kind of changes I'm thinking of please let me know! Thanks beforehand and again, sorry if this post is not allowed, feel free to take it down if that’s the case. Thanks!
