Professional valorant is a sport where if you don't perform you get cut from your team and you lose your job. A lot of these players have no alternatives with how tier 2 is fucked.
If using a judge and shorty was a free win every time, then every team would have done so instead of the "tactics" you talk about. Believe it or not it takes skill and a unique style of pathing on raze to be able to utilize the judge effectively.
That being said, there is a counter to this, otherwise every team would be judge spamming. FNS couldn't call against it this time around, plain and simple.
There is actual tactics behind it.
