ok i have been reading up on this post but stayed away from commenting but i am reading some suggestions that are probably meant to help and solve a problem some steps in the ladder seem to have .... BUT:
Being on a working part of the ladder I have to say having only 2 people on it can be tougher to play and win then having 10. If both players are going for their medal-time and tokens and are geared and buffed to fight and defend and there are no other players to 'steal' rating from when their buffs wear out. Making a minimum number of players will just turn it into an endless waiting game just like the arena is, worst case scenario it would die completely because the same 2 players from that 'pact' are the only ones opting in or even worse four players crave to go at each other but cant cause rules say we need 5 O.o
I like the idea of rewards being linked to number of participants, sounds fair and might discourage players from lurking for some tokens.
I like the idea of minimum number of hits, a player has to do X x "total number of players on ladder" hits to qualify for getting a reward.
But does 10 stam hit count as much as a 100stam hit :?
Maybe a ladder attack should always be 100 stam, only times i used 10 stam was by accident, forgot to move the slider. You could argue that with your last 48 stam you could gain 1st place again there for need the option to do an attack with less then 100. But making 100stam minimum for ladder hits together with minimum number of hits will demand more commitment to play the ladder and make farming it for tokens and medal less profitable. Might actually turn out to be too demanding and no one will play again ....
anyways what i wanted to say most is be carefull what we suggest as more rules and restrictions to prevent the abuse by some might ruin it for the bits that are working. And the best thing for the ladder i think would be many more players joining, i think it would work perfect then.
