Yeah. The thing about Chromedome x Rewind and Tailgate x Cyclonus is that their relationships felt more organic. These characters fell in love with each other but it just so happened that they are same-gender because 99% of Cybertronians are masculine. The same-genderness was incidental and thus felt unforced. They didn't make a deal of it.
Subsequent ones as you've mentioned have not been so subtle (although I personally never noticed Drift and Ratchet as a couple; I thought that they'd just become good mates). I also didn't mind Blast Off's thing with Onslaught so much, as it explored the realm of unrequited love and the fact that they were both masculine was, again, incidental. While Blast Off is aloof and arrogant, he never had a disdain for ground-based modes (unlike Powerglide who pities anyone who can't fly). But remember that Blast Off's G1 profile, as written by Bob Budiansky, also states:
"But his happiness is an act, a disguise he uses to hide his long-distance lonliness. His aloof and superior manner is a front that prevents the other Decepticons from knowing his true feelings."
So... yeah, IDW Blast Off's persona is pretty G1 accurate.![]()
