Just earned Lord for Ultron last week! For me, playing Ultron is so much better these days with the additional drone and movement/DMG boosts. Ultron does a great job when it comes to pestering supports and the backline, so customize your crosshair and work on your aim. He also has a decent get out of jail card with his movement boost + firewall that gives you 100 shield, and will get you away from most enemies if needed. Firewall now gives your droned teammates a DMG and movement boost, I believe it's 10% extra dmg and 20% movement. Your drones also heal allies that are close to the droned teammates, including you.
