If the point of the card changes was to make them more viable, I think the developers should have gone with a more in-depth approach. Maybe even a rework.
Making them more viable means getting them to contend with the current meta. If the purpose of the buffs/nerfs was not that, then I may need to be enlightened for whatever the reason was.
A lot of their effects are underwhelming at best.
And even with their proposed changes, I can tell you less than 10% will even give them a go on Normals because a lot of you long-time players like cheesing each other with high-end decks of token gen or some variation of a low-cost long-term buff strategy. That or the stall control Verore decks.
So even then, much of these rebalances will see no use. Except Marina and, to a lesser extent, Tygris and Die Another Day. Unless I missed something...
Does the management of this game even care anymore?
It's like this rebalancing was merely done to show people active on the forums "Nope, we're not dead yet. We're still alive. So let's entertain you guys with some changes you might not even care about".
