Yes, 2 is correct. Strategy should be a 5, interaction a 5, IMO. The strategy rating isn't opposed to tactics. It's a more general meaning of strategy that's something like "a lot to think about" or "brain-burning" or "get your butt kicked by good players."
You aren't drawing the cards directly into your hand and they are very expensive when they first appear. If you have enough money to buy them then, well, that's to your credit. And it's not like there's even a clear hierarchy of good and bad cards. It's all about context and how you sue them.
Now, some people think any luck is too much (at least when they lose

). [edit: not saying you're doing that - you've played a lot. Have you played IRL?]
But for me, if Pax Ren isn't a 5 on both strategy and interaction, well, what modern boardgames are?
