I think armour bonouses are a great idea honestly I never got my warden, met or frozen gloves, boots or helm till I was well into my 140's not becouse I couldn't but becouse there is simply better gear in the lux store so it was really pointless getting I mean to me this is broken. Here is the ideal I had:
Gloves
Warden - 5% attack speed boost, +2 heat damage
Met - 10% attack speed boost, +2 heat and magic damage
Frozen - 25% attack speed boost, +2 heat, magic and cold damage
Dragon - 45% attack speed boost, +2 heat, magic, cold and posion
Boots
Warden - 5% movement speed boost, +2 heat damage
Met - 10% movement speed boost, +2 heat and magic damage
Frozen - 25% movement speed boost, + 2 heat, magic and cold damage
Dragon - 45% movement speed boost, +2 heat, magic, cold and poision
Helm
Warden - 2 energy regen, +2 heat damage
Met - 5 energy regen, +2 heat and magic damage
Frozen - 10 energy regen, +2 heat, magic and cold damage
Dragon - 15 energy regen, +2 heat, magic, cold and posion
Legs
Warden - 2 health regen, +5 heat damage
Met - 5 health regen, +5 heat and magic damage
Frozen - 10 health regen, +5 heat, magic and cold damage
Dragon - 15 health regen, +5 heat, magic, cold and posion damage
BP - Damage

(make it most useful for class im a ranger so here are my suggestions)
Warden - 2 pierce damage, +5 heat damage
Met - 5 pierce damage, +5 heat and magic damage
Frozen - 10 pierce damage, +5 heat, magic and ice damage
Dragon - 15 pierce damage, +5 heat, magic, ice and posion damage
If my math is correct the elemental damage from each armour bonous build should be: (this dosent include the bonous slash, crush or pierce damage in BP)
Warden - 16 damage
Met - 32 damage
Frozen - 48 damage
Dragon - 64 damage
The nubers still may need to be tweaked a little becouse its still cosiderably less than Radiant armour, but maybe the bonouses of (pierce, slash, crush) would help offset that.
Just some thoughts would love to see this be implemented I love the storyline and armour quest but with the unvealing of diamond many people just skipped the armour quest all togaher and just use that which I feel desroyed the game.
