Meh, there are a couple of newbie-friendly supers. And that's not to be used as an insult.
[b]Radiance + Fireborn[/b]
You can't argue that a second life isn't immensely useful for a newbie. Heck it's useful for anyone, but especially if you're just starting out. The other Radiance options aren't bad for a newbie either, but the extra life is cake
[b]Nova Bomb[/b]
Ranged Fist of Havok. It's sometimes a little tricky to aim or whatever but at least you don't need to jump into the middle of the army to use it.
[b]Golden Gun[/b]
Most newbies at least know how to master a gun from their years of Half-Life and Call of Duty. So a one-shot-one-kill gun for PvP and against weaker PvE's is decent.
