Was Coil 2 and Ramuh extreme over tune?

[Triston]

Which is it, exactly?

It's both, buddy, re-read. He's chastising the use of OHKO abilities in mainstream, non-top-tier content. This applies to both Titan HM AND Extreme; tHM because it IS entry-level content and having punishing OHKO abilities that you literally cannot recover from (Landslide) there is kind of silly and oppressive to new players.
The Extreme comment is noting how the EX primals have moved out of being optional content into general play, because new players get i90 for free from dungeons, then see that EX fights have requirements of like 70 something, so they queue and get ground into dust in 5 seconds flat.
