Vile spit pretty much insta-corrupted anything in its splash radius (this radius didn't do damage to the player). People got really moany about it because it was ruining their builds or 'destroying' their world and rubbish like that. I said it earlier in this thread, but spreading apart from what it is now would be frowned upon.
If you can convince the dev team to tell moaners who are unable to take precautions for their precious builds against the corruption/hallowed/crimson to L2P and make the environment a proper threat then I'd be pretty happy.
That's actually a pretty good idea any spreading attacks maybe these whole bonus spreading towards evil could belong exclusively to expert mode so the people who whine about evil consuming everything can go there.Actually, Red and Co. have given us a unique opportunity for this. With the upcoming expert mode, there will be a "harder than hard" gamemode. While it remains to be seen if it will be a further event triggered mode, like Hardmode, or a toggled map setting, we do know that it will add new mob behaviours. So that's one place that new spread mechanics could go, since anyone going into that should already know that they are signing themselves up for the greatest possible level of challenge.
Personally any problem with biome spreading outside the jungle being vulnerable yet important in hardmode(due to the mud mechanic) has been resolved at this point, but I know some people will whine for ever...
