It was because players were abusing it that the math was made that way to prevent abuse
that is only a bad excuse for
we don't know how to store the first wave battle points for later use
so in the old way they gave those 1st wave points directly to the ranking.
and THAT was abused
if InnoGames would know how to store those 1st wave battle points they would be added after the 2nd wave
because the correct points would be
1st wave points + 2nd wave points
and given after winning the 2nd wave
so what did the players abuse ?
the stupidity of giving those 1st wave battle points directly after the 1st wave and not giving them later after the 2nd wave
that the math was made that way
too bad that they couldn't implement correct math with their skill
so the math had to be adjusted to their skill
