i agree on your last point , but u made it sound like nadia doesn't require support. She requires support just as much as a gelius. It's a team , and no unit can do everything , so yes they will need help. Nadia will require UP bateries , while gelius will require dps assistance. Actually she might even need a blocker behind her to make use of her dps.
Exk , as i said each unit can be made to look good in the right situation. Nadia is an anti swarm. Gelius is a heavy tank.Let's make a vdieo of nadia doing the golem map and compare how well she does with gelius , and see which 1 requires more help then the other
