I find the smaller Tac formation sizes really not all that beneficial. In fact I'd call it a hindrance more than a boon. Yes it's cheaper and you could in theory popcorn them a wee bit as cheap formations but to be fair, tacs are already kinda blah in EA and take a buch of cheap tac formations doesnt' actually buy you anything. It's not any less blah by reducing them to 4 stands. Also by being cheaper, the classic BTS upgraded SC tac formation isn't really possible. This forces your BTS,overwhelmingly, to be those termies you really need to have for their punch.
conclusion: I think the ability to put them back up to a full 6 so someone can can reasonably bring a hunter+sc on a tac is good. We're already without ANY armour on the list. The vanguard/sternguard are in no way a boon that make up for say no pred anihilators
2. Strike Crusiers are less utility here than in Codex and other variants.
Conclusion: One of the rare times I actually think the SC is overpriced and under usable for this list (better to self planetfall a bunch of speeders as you can bring them in on whatever turn you want). The Neil, 3 Gladius frigates was far more usable, worthwhile, and frankly fun. Not sure if it needs to come back however. The cruiser pushes the list more binary. Probably just going to be the nature of the beast.
3. In this game, cheaper Storm Eagles would have been a far better choice.
Conclusion: I should think this out better and not suck as bad at this game
4. Terminators are 0-1 doesn't scale.
conclusion: while we need to not go zany with pure termie armies and need to not use them like an extreme codex build (as in why bother having this list), there's better list design that doesn't rely on hard max. 1 termie at 3k is 'better' than at 4k game. Probably should be base on having a number of RG detachments per termie. 3 core allows one termie or something like that. That way te game scales with the points.
5. Get on the bus
Go full drop or go home. Otherwise just play codex.
