Makes sense: saves them from having to make a model.
And give all those other companies who built one a kick in the nuts. This makes totally sense for GW. All those entries which could take a pod can now take a malefactor instead - genius
If drop pods are gone then I would bet the Doom and Parasite are also gone as well for the same reasons, unless there are build options in the new kits.
No drop pods is a pretty serious fluff crash though. How do 'Nids land on the planets again?
Well, you still have the rules for deepstriking. The fluff on the droppods says they dissolve or rot away pretty quick on impact, so it's not a huge stretch for them to just retcon the actual MC out of existence. Just say that you "Deploy by droppod" and then the Droppod is destroyed on landing. No need for an actual intervening model.
It would be like building a model for a teleportation effect for Terminators: there's no need.
Now I'm not saying that's actually what's going to happen, and as I've said before, I'd LOVE to have nine of those snotpods, but I could easily see them just changing it to a deployment mode rather than an actual model.
Yeah, and I'm completely fine with that. It became nothing more than a glorified piece of terrain anyway.
The loss of the Mycetic Spore won't be driven by some sort of need to swipe at the 3rd party market (as much as some people might want it to be). Instead it'll simply be down to economics.
The Drop Pod was a risky kit because it only exists in two forms - off the table, yet to arrive; or on the table, doing nothing. It has one role, and once it does that one thing it really doesn't do much for the rest of the game other than sit there. What mitigates the risk is that it's a unit for the most popular and best-selling army and multiple other armies (Wolves, BA's, DA's, etc.) can use them as well.
The Spore though? Tyranids. That's it. They are the only army that uses it meaning an expensive plastic kit that either sits off the table doing nothing, or on the table doing nothing (unlike other Tyranid units which play an active role in the game). It's just not commercially viable, and that's before you factor in the Rule of Cool. Who wants a nice big bladed snake thing? Or a giant four armed monster?! ...or a flesh egg/pod thingy...
I'll take a big, cool monster any day, and it makes more sense for GW.
