I'm at 218k power on my main team and i don't like the system either, it's getting harder and harder to find people to kill, at this rate the event will require abusing alts soon.

There is a lot of little things that can be done to make the system better for everyone.

A) Reduce the total amount of kills required to finish with all rewards, currently you need 10+20+40+70=140 kills to finish which means i have to beat 18 teams before I'm done, if that was reduced to 10+20+30+40=100 then it would only be 13 teams I need to kill, so 5 less teams fight me a day and can now fight people closer to their power, also it gives incentives for the noobs to play more and not just get 2 daily wins.

B) If a team doesn't retreat but loses give them a point for the effort, Again noobs will be able to get more points and this will make it more worth trying, one point isn't much but it adds up.

C) Reduce the window for people to join, a smaller window means more people on at any point in time so more people to fight so less chance to fight the same team for all of my wins which means they will be less likely to give up and quit the event.

D) Increase the rewards given, make it 4 charms, 4 keys, reduce the chance for maps and stamina pots, add tactic pages ect. Make the event more appealing to do
