I did not call you arrogant. That word sounds kinda cool. I called you pompous. And you deserved it, 'cos you called me an apologist, when I expect you know I call out SP when I consider they have got it wrong.
There is too much heat and hyperbole in this thread, rather than analysis. Let's have a reasoned discussion, please.
No TLDR here, sorry. Those only interested in trolling or wide eyed hysteria can just skip the rest.
People saying that denial monsters are now worthless are exaggerating. After the changes, am I going to be comfortable attacking a faster Baba Yaga base with non-possession immune attackers? No. And if I am attacking with a Baba Yaga, do I believe she is a one turn monster? No. I possess one round then blind the next. Am I going to laugh when my team is hit with a MegaControl? No.
Does this change the meta? Yes. Pure speed denial lockdown teams become less viable, and that is not a bad thing at all. Supporters and hitters become more useful, and that is not a bad thing at all. Different rune choices become viable, and that is not a bad thing at all.
Does it change trajectory? Yes. To explain: when Freeze was first introduced with White Walker, it was a big jump from the only other denial, Stun. There were no freeze immune monsters. And it could be chained - no Recently Frozen status. That was a mistake.
When Varuna landed, with high stats, stun immunity, immense versatility, and AoE freeze, it was immediately dominant. We had to buy one and try to outspeed enemy Varuna, or be freeze-locked.
And so we waited a long time for Freeze immunity to arrive, but knew it would eventually and that we would have to buy monsters with that immunity because there was no other answer. Reptie would have sold a lot of units when it ultimately arrived, but did not give the answer, because Reptie also needed to be OP in it's own right, and it was not.
And this then became a strong contributor to power creep and churn. Each successive denial became immediately dominant because nothing could resist it, and had to be bought. In turn, later immune monsters had to be bought, and had to be powerful enough to use that immunity to dominate. And so on, until we get to Xiron (an insanely OP monster, that was a huge misstep as I said at the time).
If "Recently xxx" status effects had been a thing, the new forms of denial would have been powerful, and immune monsters would still have been desirable, but not essential. The power creep and churn would still have existed, but the imperative would have been blunted.
Introducing it now corrects an early mistake. And it is long overdue.
If I ignore the white noise from the usual suspects, I understand there to be some core legitimate complaints.
First, an erosion of trust. The community was told this would not happen, and based decisions on that assurance. How to address that? IDK. If it is possible, perhaps allow players to extract affected monsters, if they want to, for Elemental cells on full parity (eg 1770 Earth cells for a rank 5 Baba Yaga). Or allow to swap for another monster of the same tier and rank. Sounds hard to implement, to me, but perhaps something could be done which involves losing the monster if the player truly considers it worthless in exchange for something.
Second, some Traits become useless, like Celestial. That is easier to fix I think. Just change the trait. Stun Immunity and Hardened, perhaps?
Third, some skill and rune changes become needed. SP already has that covered.
Fourth, Mountain becomes very powerful, and teams that did not race for Cryotan and Igursus are exposed. Ouros was a real problem before Megastun, and Recently Possessed will exacerbate the problem. I don't much like the prospect of a wall of Mountain-kin again. Not sure what can be done about that.
Fifth, exclusive possessions become too powerful. I get that consolidating them is a problem because it undermines Abomination and because players ranked those monsters specifically to overcome possession immunity. How about, they provoke Recently Possessed status, and Recently Possessed status blocks all forms of possession (ie like Abomination)?
Anyway, can we please engage in discussion rather than name calling and gross exaggeration. We have some time to canvass the issues, but no time to waste in pettiness or going off topic.
