^^You're right badger.
I mean, I actually didn't read Elfboy's descriptions...I only looked at the pictures haha. But if Elfboy is using the word 'brooding' for 7 sx... You are right and he is right.
The 7 descriptions are way fucked-up in my opinion. Most of them have a 7w8 bias...but there are a few descriptions floating around that account for a certain anomaly...that I have only ever seen in the 7w6 sx...and yet it is always applied to all of 7 which I totally agree is complete bullshit. I don't fully understand why but 7w6 sx is very connected to 4 in some way...and I'm assuming 4w5 to be specific (as 7 is connected to 5.) And yes, 7w6 sx are known for fits of melancholy like 4s. Not to worry though because most 7w6 sx...are totally mistyped as 4s and 5s anyway.
Elfboy should be able to link you to one of these descriptions... but yah. No way is 7w8 sx brooding.
