they are just like you, have no clue what they are talking about
here is what overwatch pro said about valorant
"I'm telling you, if you've never played CS before Valorant and you're coming from Overwatch or whatever, GOOD LUCK. Expect:
1- Losing 90% of your 1v1 against players who come from cs.
2- Dying often because OW taught you to be too aggressive.
3- Dying stupidly while you cast a spell thinking you have time except that in this game the spells take 1000 years to cast and the weapons are extremely lethal.
4- From time to time making a galaxy brain play with your spells used perfectly and clutch.
Overall, I'm telling you, holding the lines, peeking etc... If you have zero experience on CS, you will be shit. I'm absolutely garbage, still managed to improve during this weekend but as soon as we play against players with a CS background i got dumbstered. In short, we will have to work really hard.
Anyway, I am realistic with all of you, CSGO players will have a massive head start they have habits that will help them enormously on the game. The mechanics learned and gamesense coming from OW unfortunately do not transition well for us on Valorant."
