I believe all the major events do this? It’s a constant tension between what is good for you as an individual and what is good for the team. Generally, the team gets more VP by attacking the team with the most VP. Generally, the team on the top has the highest number of active defenders and a greater proportion of higher bases. So, if you cannot take out the top dogs, then you scroll, and scroll, until you find the guy worth 90 points that you can take if he’s got one defender.
So, I would not say the Bonus Meter did anything that the events themselves do not already do.
