So today I decided to try out the chem class in survival and I guess I'll give my take on this class. First and foremost I played only the left tree being desolator in all 3 of my survival games and well I got to say that this class is a bit op and does quite a bit of FF. In 2 out of my 3 games, I ended up tking accidentally because team mates unfortunately ran into gas or ran into the tier 3 skill Aoe effect. My take on the gas skill is that its a more powerful version of the Medic's t3 Nano Sear considering it does 40 dmg per second and adds venom stack. So I guess that needs a little balancing there. The t3 skill I think is a little op because I believe that I was able to one shot Ivax using that skill from what my team mates were able to tell me and see, although I didnt see it myself. Essentially the tier 3 skill is like a mini shiva considering the AOE dmg it does on top of the inital blast. So all in all, I really do enjoy playing the class but it does need a bit of balancing. I personally think that there should be something done about the FF elements because of all the possible accidental/purposly tking elements with it. If its possible a suggestion could be adding a new item being the gas mask available in game and the credit store for a low price so that players can avoid being accidentally killed from the gas. I also added a replay to this post, so enjoy.
