This is for the people who brought the starter edition...

If you brought the starter edition, your best option would be to pick 10 operators since base game operators cost 12,500 renown each. So 5 operators each for attacking and defending and the 10 that I'm about to list are possibly your best bet to having the best experience in Rainbow Six Siege.

For the attacking team
Sledge - If you are absolutely new to the game and you don't know where to start, Sledge is one of the best options to choose from. He isn't a hard operator to play with (Considering his name, you should know why...) and the team doesn't rely too heavily on his gadget.
Thermite - One of the best operators in the game because of how good his rifle is with low recoil and high damage. His gadget is also one of the most useful in the game especially for creating a on reinforced walls. Though, to create that hole, you have to make sure you stay alive, the team relies heavily on him to get into the objective but if it's jammed or electrified...
Thatcher - Thatcher is your main man. One of the biggest problems you'll face as a Thermite are Mute's and Bandit's gadgets which jam or electrify reinforced walls. With Thatcher, all you have to do is throw your EMP grenades and no more
Ash - She's one of the fastest operators in the game and literally has no hitbox. Her gadget is breaching things from afar, pretty much a breaching grenade laucher which sticks into any surface. Just remember that you'll be called a sweaty try hard from time to time...
Twitch - Now this may be a controversial pick since her drone is about to get nerf'd but her rifle is what keeps her on this list. Her ability isn't that special, basically a drone that can't jump but can shock people and destroy their gadgets. However, her F2, a variant of the Famas, shoots around 980 RPM and it's possibly one of the most deadliest assault rifles in the game.
Fuze - Now one of the things I forgot to mention is that when you buy the starter edition, you get 2 random operators. One of them may end up being Fuze. If you do end up getting Fuze, I'd still recommend gettinng the rest of the operators I listed anyways. He isn't bad by any means but if you do end up getting him, don't play him on hostage. His gadget is a cluster charge that spews out multiple grenades, effectively making him a room clearer. He's a flexible operator with many options, a rifle, LMG, and a shield.

And now, for the defending team
Rook - He's one of the easiest operators to play and helps the team just by dropping a pack of armor. That's all you have to do and you get to survive one extra bullet and will mostly be put in the DBNO stage instead of death. The only thing you have to remember is to make sure you drop armor in the beginning of the round which a lot of people forget...
Bandit - Bandit's gadget is pretty simple to use as long as you use it on reinforced walls since his gadget is the only one that can destroy Thermite and Hibana's charges on contact. Also, his MP7 is known as a god tier gun, being incredibly easy to use.
Jager - Aka the ultra sweaty try hard main. To be honest though, there is a good reason why people main this guy and that's because of how good he is. His gagdet may not be that useful at times, having the ability to destroy any type of throwable but I like to call it wishful thinking. Another thing to help him is that he's currently the only defender with an assault rifle so he gets to do more damage than most defenders which only carry SMGs.
Smoke - He's simple but somewhat hard to use. See an enemy trying to get in? Block him out with gas. That's why he's called Smoke. He excels during the last few seconds of a round when enemies are desperately rushing in.
Mute - He almost works in the same way as Bandit but his gadget has a radius meaning he can block off a Thermite's breaching charges on two walls. He also has the ability to place his jammers anywhere where as Bandit can only place his on shields, barbed wire, and reinforced walls. He is one of the harder operators to play if you don't use him correctly so I'd recommend learning him soon.

Honorable Mentions
Hibana - She's an attacker who serves as an alternative to Thermite. Her gadget is a mix between Ash and Thermite, being able to shoot out 6 pellets and burn through reinforced walls. She's a flexible operator and her ability can be amazing at times. She's a DLC character so she will cost 25,000 renown.

So do I recommend the game?

Absolutely. Even if you buy the starter edition, all it really means is that it will take more time and patience. Siege has a huge learning curve but once you get through it, you will be hooked. I hope this review helped, took me a while but I just wanted to share my thoughts.
