She is asking for pros and cons... Simple "I like the idea"s or "Format lololololol I like the idea btw lolololol"s aren't helping that much...
Pro:
Longevity of newer players... Many players quit or change worlds after being farmed early in-game. Allowing them more time to build their cities and armies allows them more time to catch up to large players.
Con:
More experienced players may not join the worlds... Many very aggressive players might be angry at this change. These players like to strike EVERYONE soon after BP ends.
For New Worlds:
Beginners Protection should stay the same and then double after a week into the world...
For instance, BP lasts 5 days on world Xi... 7 days after the world opens BP will be changed to last 10 days.
