(Rainbow Six: Siege) What do you like (or dislike) about R6 compared to other FPSs?

Personally, for me, it's the level of tactics that are involved when you're playing seriously with a team. I remember sitting on discord for hours with my guys and planning out our strategies for our ESL match on Oregan. Loved every second of the detail we went in to.

What about you?

I dislike the new hitpoint system or whatever you call it. I remember that a few years ago the kills weren't that easy to get; you wouldn't have to just press m1 and voila you get a kill.
the system required actually the attacker to hit more times than just 1 shot
