I literally told you how to adjust your play to suit VH and C9 in my first post in this thread.
I'm harsh because there's no point in coddling people who are complaining about things that are not actual problems. They are problems because they lack skill and knowledge, *and the best way to gain those is to actually go out and play more games.* Sometimes someone telling you what you need to be doing can help, but Crystalline Conflict is not a complicated game mode and none of the classes are complicated, either. If you are intelligent enough to find your way here and to create a post, you are certainly intelligent enough to arrive to solutions to your problems on your own by just playing more games and swallowing your desire to complain about things in favor of just playing more games.
A lot of getting better is just learning to analyze things. What killed you? Why did it kill you? What sequence of events lead to that killing you? What could you have done differently? At what points could you have done something differently that would have prevented your death? And you also do this for kills - how did you kill them, why did it work, what could they have done differently to prevent their death, what could you have done in response to them trying something else to ensure they still died, etc.
It's actually the same process you engage in to become better at a real-world job's skills, or to actually remember and take in what you're studying in classes, etc. In a lot of cases, it's all just automatic. But sometimes it helps to take a moment to digest what happened, especially if you feel like you did nothing wrong but still lost. Many times, you lost because your teammates screwed up - but you can't control that, so it's pointless to try and analyze it until you're confident you aren't making a lot of mistakes in your own play. Fix your play first, and then once you do that, you can try to apply the process to what your teammates were doing. Doing this helps you understand other classes, even if you don't play them. It's the equivalent of using flash cards or other processes to help you memorize and grasp a subject prior to an exam or something.
I'm not interested in sugar coating things. Doing that does not help people improve, does not give them what they need to improve. Sometimes you just have to admit you aren't very good, and solution really is to just "git gud." Like I said, it's not a complicated mode. Spending less time complaining and more time playing, and analyzing your play, is going to get you better results. If this game had replays, this is where we'd go "upload a replay so we can go over this game with you and help you identify errors", but sadly that's not an option. But if you reach a point where you're genuinely mystified what happened, you could always record/highlight a match and then share it here. That's the closest option we get.
