Class and Level Geekery XVIII - Everyone's an Expert

[Quartz]

I note that we still have Roy listed as having Endurance, due to sleeping in armor without getting fatigued, but this is neither RAW nor (I think) RAI for heavy armor, which Roy has been established as wearing several times now (panel 9 and panel 2),

I think in that strip Belkar isn't referring to the class of armour there but its sheer mass (remember that it would indeed be very heavy for him). I think we've only seen Roy with breastplate and pauldrons (classed as Medium Armour in the SRD) - I'm thinking of that scene with Celia after his resurrection - so it's entirely possible that Roy has, in fact, Medium armour. And thus the Endurance feat.

TLDR: differentiate between armour being heavy and armour being Heavy Armour.
