It might just be your server or the specific people on at the time. I make it a goal of mine to be extremely friendly. Welcoming new people, helping others out, greeting the housing area when I come back, etc. Most people respond pretty warmly once they realize I'm not trying to troll.
Your HP is a bit low. You could do well to replace that weapon/shield or ring with something better. The echo buff should kick in after a few failed attempts, so you don't need to do anything drastic. Maybe eat some vitality food.
However, remember: Titan is a fight of mechanics. You win or you lose largely by your personal skill. If you're getting hit by landslides/bomb, or if your group is being awful with plumes, then you will die regardless of gear.
