...but also consider that as a neutral rager, your enemies are much slimmer than an evil rager. And a goodie rager is hard to play (what to do about elf mage?)

So by that, a neutral rager can keep a good set longer than an evil rager, in most cases, because while he might have empire/scion/nexus ganks to deal with, he doesn't have fortress ganks thrown into the mix.

Also not being a dwarf/mino neutral means less enemies, too.

But yeah - imperial fire giants wielding armageddon hurt lots.
