Some time ago I actually proposed trading LR for:General question to those talking about defence as a differentiation to other elves:
If HBE improve their defence, will they e.g. lose lightning reflexes? Anything else?
Or will the whole book just rise in individual model eliteness?
Does this latter not just make you "better versions of the other elves"?
Stoicism (or any other cool name): model parts with stoicism gain parry, +1 Armor and +1 Aegis.
The reasoning for that being that HBE were just short to the top5 for armor, were also high in special saves and high in avoiding damage traits and this rule quite neatly encompasses being JoAT in defense, while also reducing their face blending offensive power as a tradeoff.
