i see a problem with a team holding the ball for too long, wether it is a hard reset or a struggle in a board, when the games are designed to be 12 min with no stopages of times
depending on how the ref will handle in between goal scored protocol you might loose 20 sec by making sure “every one is ready?” ( this issue is adressed by the nah proposal of 15sec countdown which i would bring to 10sec personally)
which means if there is 6 goals scored (3-3) you loose up to 2 min actual game play. so games are even shorter than what they already are.
there is two type of defense , are you being led by score or are you leading ? if someone is leading you 1-0 after a very hard earned goal then the leading team might play very safely.
its harder to push a team leading you 3 up since you already 1 goal led. its easier to choke a team 3 up if you have the lead.
the game can be re think to the ground with the addition of timed play, you might increase the crease size , you might disallow hooking mallets to balance . time clock will force players to be more effective in their play style and find solution collectively to bring their team to a scoring opportunity .
one last factor is court size , ruleset stipulate something around 35 meters x 20 meters but if you end up playing shorter courts (30x 18 for a basket ball court / tennis court) , a third line for reset doesnt make sense since its the only way to spread open the defense widely enough.
the bigger the court , the more effective passes are. small courts will end up in a lot of hard shots taken half line since 1/ rebounds are dangerous if you play 2 up and left open after a pass 2/ hard rebounds are in your favor if the ball goes out of court
