You can break the top 100 just by pushing to string the top titans in the game and winning more wars than you lose
Just put reqs in place that flow with the majority of the team(or the minority if you feel the majority aren’t up to snuff)
Continue to up the reqs as you guys progress
Weed out the inactives and those that can’t keep up roster wise
5% titan decay happens daily at the time your alliance was created
You can kill 2 titans in 24hrs to temporarily inflate your score and even do that multiple times but since the 5% decay gets bigger as your score gets bigger, it truly is only a temporary inflation
Increase cup reqs to over 2400 helps alliance score too
Also war scores are the main separator in the top 50 and that score is mainly constructed of rosters
I have the data to crack down to the point values of 5* and 4* heroes, along with troops but haven’t compiled and analyzed yet
But simply just try to get as many maxed 5s into the alliance as you can is easiest way to boost war score. Eventually requiring x level troops helps as well but idk how much for that yet.
War score past performance goes back 10 wars. New Victory/loss replaces the part of the score from the 10th war back. So if you fight 10 in a row:
L W W W L W W L W L
Then 11th war you get another win, your past performance score will go:
W W W L W W L W L W
And score will reflect that so eventually you get to a point where you only see your war score change after a war when you replace a loss with a win or a win with a loss, so 10 wars(this is outside of roster changes or player changes)
If you reset that by starting a new alliance, you very well could drop bout 4 or more competition brackets theoretically since the matchmaking system tries to match alliances within a 500 range and you just dropped about 4 to 7x that possibly more depending on wins(i forget exact point value of wins and losses, in a note buried somewhere)
If you’re pushing for top 100 though, i wouldn’t advise resetting your war score every chest
