It’s WoW. Does that REALLY surprise you?
Now, I get it to an extent simply because I’ve taken part in transmog contests hosted by streamers, some of which have had prize support (winning one is how I got my second TWW CE for my EU account)
When you’re taking part in a contest, the basic rule is generally a max of two pieces from a single set. If you show up rocking a full set, you typically aren’t going to win as whoever is hosting it and doing prize support KNOWS that the guy that spent weeks farming content to put together their perfect mog doesn’t want to lose to the guy that threw together a basic set in about 20 minutes.
I can understand the complaining if we were talking about something like that, but Arc is literally throwing a temper tantrum over the Trial of Style. Frankly, it’s ridiculous.
