Hi I suppose that similar posts to this one were popular but I couldn't find anything, so I'm really stuck and I don't want to waste any of my mats for something I definitely wont love. Im stuck between choosing trailblazer and viper as in title. I really want to do open world champs easy but also I want to be able to play raids or other pve content using the same gear if its possible. What gear will be a good choice? I got enough items only for one, either viper or trailblazer. Help pls=)
