As you know that twinks were separated from regular leveling player queues. However, they started to exploit scaling where they stop at level 20 and get sets, scaling make them as powerful as being a 29lvl twink.
Taking advantage of scaling is an exploit and should be a bannable offense.
I saw this video the other day where a level 1 twink beat a level 12 character it was great. I have never made a twink and never will but it’s a fun concept, who cares?
