As a follow up post, a 51 paladin fighting lvl 47-48 mobs under the late velious era AC system should classically take an average hit of 73, be hit 50% of the time (after skill evasion). This is what was posted by a live dev just after it was revamped in the luclin/pop era (

Anyway, TLDR; Armour for xp content seems to be working as live did. Both classes can mitigate/avoid okay early 50s. Ranger perhaps slightly weaker due to less hp?
