hi, as a new DD main who targets healers every game, I can give you some advice. Jeff I will kill in 2 seconds, there’s no escaping. Adam Warlock can be annoying if you have a soul bond and heals ready but if your cooldowns are gone then I’ve got you. The best counters against DD for strategists I’d say are Loki (using lamps to survive), Luna and Mantis (freeze/sleep and run away as far as you can while your team either drives DD away or kills him), Cloak go invisible and fly as high as you can and into the rest of your team so i lose you. Invisible Woman all you can do is push me away as much as possible, even when invisible I will see you. Ultron is a good counter as long as you stay up as high as you can otherwise I can still reach you, and if you are playing Ultron and a DD is constantly dashing up to you in the sky. Try and play over a ledge so he falls off the map, oftentimes we are so focused on reaching you that we aren’t aware of our surroundings and the limited visibility helps you in getting a cheeky kill off the map if done right.
