1st star : 50%
2nd star : town hall
3rd star : 80% or even 90%
4tg star : 100%
With 4th star rating system this will not affect to much on th 9 or below that, but it'll bring more competitive game, more balancing judgement instead of more balancing troops and defense, and more apreciatiation to the player who can do more than 2 star attack but pretty hard to do the 100% attack.
The gap between 2nd star and 3rd are far enough for upper TH (th 10 & 11) nowadys. This is one of the factor there are 2 stream players keep asking for nerf troops and the other side want to maintain it. What is the point of the players who try really hard to do 100% attack and fail at 90% 2star result and the others spam dragon and get the same result : 2star attack. ???
Well, this is just my simple thought.
How did the other members forum think of this ?
