This is a bad way of thinking about it and you are again missing the point.
I did not miss your point. I addressed one thing you said. I think it is silly to think this is anywhere near impactful for new players.
I see you've chosen to regurgitate the rest of the post, so I'll address a bit more this time.
It's not even about if Ice Rager or Evil Heckler are good enough to be played in Constructed as is... it's that it sets a terrible precedence.
Soon we will be seeing 5 mana King of the Arena, 2 mana Stoneskin Gargoyle, 2 mana Dalaran Mage etc. Eventually some card will get "buffed" that MIGHT ACTUALLY see constructed play and it would be a bad look for Blizzard.
Why would it be bad if ice rager found a place in constructed play? That is kind of the point of putting new cards in the game. Maybe 5/2 is good enough for a specific deck. Maybe not. Who cares if it looks bad for blizzard. I don't even see how it looks bad for them to release a card that actually is worth playing.
It also shits on their previous statements about "well some cards are bad now but could be good later so we don't change cards".
I'm almost absolutely certain they've said they would release new stronger cards before buffing old cards. So this doesn't shit on their old statements at all.
Well by introducing the Evil Heckler you are pretty much admitting that Booty Bay is in fact a horrendous card (at least they think Magma Rager is a joke and a cornerstone of the HS community so we can give one card a pass).
I'm pretty sure they are okay with booty bay being a bad card, the same way brode admitted war golem is a bad card.
Why didn't Blizzard make Booty Bay into a 4 mana 5/4 instead? Because they don't want to look like fools when they made a video talking about how they don't want to buff old cards because it confuses returning old players and it takes too long too test cards.
You just gave a potential reason. They don't want old players coming back and being confused at least fits this narrative. Seeing ice rager they will understand it is a new card with stats to be learned whereas if they see magma rager at 5/2 they might be confused.
Well many streamers are calling out Blizzard on their bull shit now. And rightfully so.
Eh? Many streamers? I'm seeing conversations about patron warrior, not silly concerns over power creep because two of the worst cards in the game are outclassed by other cards (always have been, always will be).
I think worrying about how Blizzard looks because they released cards that might actually see play is just silly.
