the troll armor would be viable is stealth were easy to determine what is effective stealth and not. i know before this update when i tamed wolves i used a set of troll hide to keep hidden more easily. but when i fought wolves, drakes, and the boss i was in full iron. so i guess it all depends on your approach. if your gonna go slow and steady and clear your way out first, troll hide can work while you work for a set of silver armor and weapons, but else, get some iron pieces made and upgraded. only thing i made of bronze is the axe, i dont make the pick until i get iron since antler can be repaired anywhere easily.
