It looks like a fun feature and not an actual advantage over other players. I see no reason to ban this feature in AoD or SMP, feel free to use it until further notice.
Hmmm Creattive round is here, so I could pick jack o lanterns.
These glowing pumpkins then AoD hunters could be easily spot in darkness, on other hand optifine all just needs is install forge and then copy optifine to mod folder. (Its Dynamic Lighting option under Video/Quality settings)
Or we could swap hunters jackolnatern with pumpkins.
I think it would be bit of advantage on dark maps - if you could see moving light source, it would mean either its survivor with torch or hunter.
Eh click this
link since imgur album just puts screenies randomly in album.
