If you are , skip Kovaak’s. Your issue isn't your arm; it's your crosshair placement and peeking technique. The Range is better for you.
Here is the hard truth about using Kovaak’s for Valorant. In a Valorant match, you might take 30-40 gunfights in 40 minutes. In Kovaak’s, you can take 200 gunfights in 10 minutes.
For every pro who swears by The Range , there is another (like Hiko, Asuna, and TSM ImperialHal) who swear that is the reason their micro-adjustments look like aimbot.
Kovaak’s teaches you to react to floating blue spheres in a void. Valorant teaches you to pre-aim at head level while clearing 50/50 angles.
If you rely on Kovaak’s flicks, you are playing "Whack-a-Mole." The best Valorant players don't flick—they move their mouse 2 millimeters because their crosshair was already there. If you want to see your Ranked RR go up, stop grinding "Tile Frenzy" for high scores. You need Valorant-specific scenarios.
