OOO should add a Fire version of the polaris which i have named the "blaze burner". the gun does elemental damage like the polaris but sets sets things on fire instead of shock. it wouldnt be OP because the damage from fire is pretty much the same as shock, the blaze burner wont be an OP version of the polaris just as the magma driver isnt an OP version of the Storm driver. the gun would look like this : http://img190.imageshack.us/img190/4096/blazeburner.png ( good photoshopping this time )
the 3* version would be called a "temperate pulsar" and the 4* i havent thought of a name yet.
and the reason a fire version of a polaris would be good is because some people cant shock many enemies but still want to use a pulsar type gun and still inflict a damaging status.
What do you mean not shock enemies?
Polaris is already powerful enough, adding a clone with unrestricted knockback and extra DPS would break what little balance exists.
