It was basically horde meta before knight meta came to pass. Storm bolter WG and razors have been staples forever so I’m not too worried.
I don’t see too many people going out and buying a green tide though if they didn’t already have it. Orks really never went away, they’ve been scary this whole time if you had the right boyz around...
More than just orks are coming. Local IG in my area are considering alternatives post FAQ.
I ran into a max model brigade detachment of vostroyans in a narrative campaign and the guardsmen were never ending. Morale immunity from a relic meant i had to focus fire and kill it all. If i killed a unit in that fashion it came right back with "send in the next wave" anyways.
They covered the entire board like ants (move move move is insane).
Even if a knight soup army fired everything it had it couldn't erase guardsmen fast enough and the point tradeoff is always in IG favor
My armies can deal with knight stuff. I need more tools for hordes (orks and others)
That never went away either though, it was always good. Thats been the classic weakness of marine armies, masters of none. With knights and crazy cheap stuff the gap has never been wider.
Hordes will always be harder to deal with IMO because they can daisy chain and we cant take them off obj due to obsec numbers.
