This will be a hot take, probably rude, but it looks like the only Jmod fighting these bosses is Mod Camel and he's above average at best and average at worst.
Either that, or they need to hire Chris L back to teach them how to do actual bosses, or let Orion Take the wheel (which i would rather much prefer because ED's are the best bosses after Rax).
The actual playerbase cannot really kill Araxxor, and they rarely touch Telos, let alone above 50% enrage (not even 100%), so it's time for them to start asking streamers for help (both casual, average, elite and knowledgeable), the more viewpoints the better.
I'll take above average xD I put quite a few hours into learning Telos before the release so I could better playtest Raksha. Still quite a bit I need to optimise though :)
