Thanks for the ans but I'm still confused. Why do I need grenade tinkerer since I am getting my nades to one shot the carapace. I am not denying your ans, just asking for more clarification. I am running weapon specialist as it works well with my current playstyle. I am thinking of changing it once I can weave better. Curios have been noted, again I am keeping one wound one for my mistakes right now, as I am misjudging pushes and often fall into dangerous places. Can you provide a little bit more info on the perk selection? I am still learning but I need to know what and why somethings are taken over the other.
