My personal favorite is Rainbow Six Siege
^^ Definitely same, favorite attack and favorite defense operator(s) and why?
I think I have like 120 hours in the past 2 weeks game play on Rainbow6;
Favorite attack operator is rather conflicting to me, it's either Ying, Maverick or Jackal (Jackal can be played a lot better than how most people play him, he basically has very high awareness of where people **could be** even without scanning), Maverick can be played so amazingly well with a lot of different smart plays that can be pulled off. His gun is pretty good too.
Ying's Candelas are amazing if you wanna just rush in - she even got buffed, getting 4 Candelas instead of 3!
Her LMG is REALLY good. I mostly use her for her LMG, admittedly. It doesn't feel like an LMG, it feels like an AR with 80 bullets (instead of the usual 30)
Hibana is also pretty good if you know how to switch between her main and her secondary really quickly! Her ability is very useful as well, it's the best for getting reinforced hatches as well.
As for Defense, I feel like it's kinda map oriented. I love Echo because of his Yokais which you can use for AMAZING things. You can counter Montagne with Yokais, stop defusers from being planted, watch a door (preferably one that has a shield on it to slow down the opponent while rushing in) then sonic burst the one person coming in as you instantly peak them. Plus, you can use Yokais in the map Bank for amazing spawn peaks or early intel.
Lesion is really good, despite me never using him yet, I feel like I'll like him because:
Besides his good guns, his ability is slowing down enemies while making a sound where you can hear from a long way. What this means is you can watch an angle and not worry about people rushing you from your right, because you'll know if there's someone there, once they step on the GU mine. And it's nearly invisible, so you don't have to worry about people destroying them.
It's also a pretty good counter attack for Montagne. If he steps on one, he's forced to lower his shield so he can remove the mine slowly killing him.
I've been meaning to use Mira lately, so I can try to hide in corners without anyone seeing me. I bought her earlier today, hopefully I could get some funny epic moment out of her u.u
