The usage on passive/skill trees is almost 50/50 and it makes searching the trees much more difficult than it needs to be. To wit:
Forge Guard passives using 'armor'
Forge Guard passives using 'armour'
I get it. I played PoE for way too long too. The UK spelling with the added 'u' is almost reflexive for me as well. But it would be rad if we could just pick one spelling and run with it.
