thanks for the reply. Question about Armor/Shield. Is it worth going for a tier 3 defense with heros like Ringo or Gwen??

Hey guys I just started playing vainglory about two/three weeks ago. I'm looking for a little help/advice/tips. I've been looking at builds for certain players. I think I'm missing certain fundamentals and knowledge of the game. For instance, what is the difference between building a crystal build vs a weapon build? Like does crystal damage affect certain heroes more than others? And if I look at what my opponents building, should I alter what I'm going building??
