Engineering on NFTs are pretty much is the strongest stat you can get from Terracore NFTs. They were strong before but with recent mining rate change they become a whole another beast.
What do I mean by that? Well, if you have one NFT that gives +1 Engineering you might not notice anything. But at +5 engineering your upgrade time gets cut to 16 hours from 48 hours with 0 engineering NFTs. At maximum theoritical engineering of +25 your engineering it gets dropped to 4 hours for an upgrade.
You, of course, still need other stats to take advantage of engineering NFTs. But even then when you can upgrade your stats in a couple of claims, it shouldn't bother you that much. Especially, if you are at the top of the leaderboards already.
When you can pump out thousands of scrap and open ton of crates, hunting bosses to get lucky doesn't matter that much. When you open hundres of common crates you are bound to get lucky and get rare and up items anyway. You can still 2 sets of items, of course, one for boss battles and one for that sweet mining rate. But you can still do without luck, and just engineering.
That is what I mean by Engineering is all you need (in NFTs.) I will leave the iterpreting if this is bad or not to other players.
This is an example table of engineering, now think about how +1 engineering and +5 engineering affects this table and think about the same affect at a higher level of engineering.
Well, I don't like to drag on my posts and overcomplicate things. So, I'll end this post here. I would like to hear about what you think about engineering NFTs. So we can have a discourse about it.
