It really comes down to personal preference. I'd rather maintain more movement speed so I don't use bronze armour, I stayed with Troll armour on both characters I play. One has a bronze shield, but that's it. I only have a bronze axe to chop trees, I rarely use it as a weapon. The tier two troll armour (one upgrade per piece only) upgraded club, upgraded bone spear, and fine bow have been working just fine for me even through many players fully upgrade a full set of bronze before really tackling the swamps. It all depends on how you play and whether a bit more protection is more important to you than mobility.
