Baron Buff Change?

Okay, so I've had this Idea for a while now and didn't know where to put it so here goes. As we all know, getting Baron can make or break some matches, especially with a split pushing champion who just smashes down almost an untouched Lane for the win (I hate yi..) So my idea is instead.of Baron Buff being what it is now where minions are buffed with your presence, instead have them buff only by a percentage for each nearby champion with Baron. That way, you are forced more to fight as a team to get its full potential, split pushing is alot riskier and it is alot more important if one team member loses Baron. Maybe have each member give minions just 20% of its buff, although the self buffs would remain the same. I just feel alot of the time, the team objective on the map is not often used as a full team, or it over powers some split pushers too much.

This is my first idea I've brought to a forum, what's your feedback?
