Someone might have mentioned this before, i don't know
There are quite a few players capable of scoring 600 points and more.Raiders in top 3 raid actively and many times cross 600 point mark.
There are also many players who want to be in lower ranked alliances for sake of getting lvl 3 box easily with less raids . So with the lvl 4 box at 600 points , if say about 3-4 or more raiders in lower alliances raid for 600 points that would bring the low ranked alliances a bit high with extra 1k-1.5 k pts or more and 'MIGHT' open up their alliances for the higher ranked ones.
So i think that there should be lvl 4 war reward boxes for 600 points with 250 -300 fuel and tokens/keys .
Please share your opinions too.
