I dunno just my opinion, i think with 5 people using flamethrowers the runs go faster than with guns, maybe not twice as fast, but faster.
There are credit flamethrowers, so not having plat is not an excuse to not be able to level up alts.
The spirit of the event was to get a flamethrower and break 2 million eggs, not level up your alts (which was and still can be done in the event maps, just not as fast as before), people weren't getting xp with flamethrowers, obviously that was wrong and needed to be fixed.
I don't know, i don't care. I gots me some eggs to scramble!
