What to buy? (Tom Clancy's Rainbow Six: Siege)

Valkyrie

She rules?

Depends which side likes to play.
If you like for the attack to play it OFC Capitao-he's good.And Def Yes,Val cheerfully.As Daimond suggest.

I'm for both sides are well played.

Yes, take all, rules of Opera, and so 1 take the Valkyrie.

I Kapitoshka I took like not bad.

Briefly about the characters and his guns:
Tank, medium, the hero of speed and armor, with regard to guns, guns have very high recoil due to the fact that you can not put a vertical grip
-Valkyria, also medium armor and speed, this gun is very imbaba in terms of recoil and range, small damage, very good hero
-Kapitoshka, hero assault, fast but little armor, good gun, damage and impact, as well recommended to buy, after Valya
-Frost, srednicach, the gun is not ice, but not for everybody

Best Valya, Captain, frost and lastly Tank to buy
THIS IS JUST MY OPINION, IT MAY VARY WITH YOUR
