By what objective measurement?
By winrate? Reno Warrior is a Tier 2 deck so it is better than 50%, but it’s not Tier 1 so there are bigger fish to fry.
By polarization? Once again Reno Warrior is a little above average but there are far more polarizing decks like Dragon Druid, Aggro Paladin and Rainbow Mage.
By popularity? This is the only metric where Reno Warrior is on top, but if you ask me popularity is a metric of design success, not design failure. A lot of players are drawn to Brann and think that he’s cool and fun. Nerfing things just because they are popular is Bizarro World logic.
So what is it then? Seem to me to just be some irrational emotion you feel when you look at the card. Subjective and mostly meaningless.
If I was in charge of balance patches Brann wouldn’t be getting nerfed at all. I consider Reno Warrior’s popularity and winrate to both be flukes from the perspective of being concerned purely with winrate, and I consider its popularity to be a general indicator of good and popular design from the perspective of… well, design. And I am certain that even if Brann was deleted from the game, the deck that you think is being held back by Brann would still completely suck.
They can both be problems. I think one issue is that a lot of people playing warrior counters haven’t been playing them for very long, and it takes them a while to learn the deck. Crescendo Warlock seems like a difficult deck to play to me, so there’s going to be a lot of people who pick it up, play a handful of games with it, bomb because quite frankly they’re bad players and can’t handle it, then they quit and go back to whatever they were playing before.
There are situations where you already have the other copy of the weapon or Void Virtuosos in hand, in which case the card is redundant and it’s the right play to throw it away, but those are somewhat rare, especially before playing the first Insanity. It’s the kind of thing that’s the right play maybe 5% of the time and the wrong play 95% of the time. Harps and Virtuosos are very good against Reno Warrior so you want each durability on a Harp to prevent 3 or more damage if possible, maybe two 3+ and a 2.
If you see a turn 4 Insanity for 1+2 against Warrior with a Harp first, that’s basically a guaranteed misplay, it should be Insanity first then Harp. (Neither is really good but sometimes the good cards just don’t show up.)
