Do you think the card I mentioned is responsible for it? But I mean, why does it matter anyway. People's kneejerk reactions killed Ancient of Lore too.
Let's throw out the baby out with the bathwater already, at least people will stop it now and finally move on.
Innervate? Hell yes. It's a big part of why druid is broken and has been tier 1 almost throughout the history of the game. It also immensely impacts card design as it affects druid minions, spells, and even neutral minions in a big way. Having ramp and innervate in the same class was a mistake.
Also, kneejerk reactions definitely did not kill ancient of lore. That was not even a highly criticized card in terms of being broken or OP. If anything people correctly pointed out that it's too ubiquitous and that is the reason why it was nerfed. It's not even like Druid suddenly became bad because of the combo and lore being nerfed, the class remained largely top tier in one form or another.
People have been calling out innervate since classic. If it takes them 3 years to finally do something about it, it's far from a kneejerk reaction.
Innervate in the basic set make this a very awkward situation as HOFing it likely isn't an option.
I don't think they're afraid of HOF a basic card. They have many options, I don't think they'd categorically shut off one as an option. It just makes other options slightly more appealing imo.
