I'm really shy so it's hard for me to compliment people IRL, but on Valorant, I like to be nice to people since it makes the games more fun and everyone feels better in competitive environments that can be toxic. Mainly, treat others how you want to be treated, but I just thought it'd be nice to share what I specifically do:

• Whenever teammates pull clutches, aces, etc...I bombard them with comments like "legendary" or "you're so good" or just "OOOOOH." It sounds obvious to celebrate whenever this happens, but even when your team just win a round in general, I like to say "nice job" to encourage the everyone.
• Type "nt/nice try" every single time a teammate is the last one standing and fails to clutch because it acknowledges their effort and also lifts off the pressure of not being able to win a round for your team. I know that for me, whenever someone tells me "nt," I feel encouraged even though we lost that round because it lets me know that they appreciate the effort even though I suck, and I don't feel judged or blamed for losing the round.
• It always sucks when the enemy team gets an ace, but when they do, I congratulate them with a "nice ace" anyway, simply because it's nice to do. It's always cool and exciting whenever someone gets one, so I like to celebrate it with them as much as possible.
• Whenever someone starts flaming a player for performing badly whether they're on your or the enemy's team, I try to encourage them with words like "don't listen to him, you're doing fine." IMO, it's generally better to address the person getting flamed than the flamer because it incites less toxic drama and still gets the message across that it's not okay to be mean.

Lastly, this is a more personal thing that I like to do so feel free to ignore this part, but:

• Occasionally when a teammate is bottom-fragging and requests a gun, I'll buy it for them even if I might not have sufficient funds to buy for myself that round. Of course econ and investment is important in the game, but I know that I appreciate it whenever someone buys me a gun even though I'm not a very good at Valorant, so I like to do it for others too. Obviously this applies more to Unrated matches than Comp since you're risking less.

I know that this post is just mainly stating the obvious and that I probably sound pretty naive, but I think that kindness is important everywhere, even in gaming. So yeah, let me know what you guys think!
