I have a 31 warlock and a 29 Titan. My Titan needs Titan mats and exp. so I shoot everything. If you speed ahead I will catch up but I will be killing everything as I go. Dieing to have me spawn where you are is selfish. That said my warlock doesn't need mats. If the group rushes through everything I'm game for that. If someone lags behind killing stuff I will stay with them and contribute. This game is way more fun if we all communicate with fellow guardians.
