Except Ultron's ult is not bad at not even remotely top 5 worst ults.
It's a flexible ult that can heal allies (625 hp/s~ x 5 full duration) or kill/pressure enemies (125 dmg/s~ x 5 full duration) at a distance and dynamically, while healing himself 50 hp/s and still allowing him to use other abilities.
Sure sounds pretty terrible, you're totally right.
