What about having a stacking component to the Baron buff?
not for number of kills, but for number of players nearby who currently have it
minions would get a lesser version of the buff if 3 teammates were empowering them, compared to a full team of 5 having the buff
it would take some pressure off of split pushing, having slightly weaker minions with one member top and four mid, as well as more of an impact when members die while taking the objective itself
killing an enemy with Baron buff would not only reduce the number of threats possible at once, but also the effectiveness of the threat
just a thought i had what do you think .3.
