That style of play would certainly drive away first timers who were paint shy, I agree 100% Renters and new players typically do not seem to enjoy that intensity of balling. Even some of the guys I play with, who have played all levels of ball would walk away from that - from a 'been there, done that, not interested' point of view. I certainly always feel bad for the renters/new types I see at Spring Castle, because it is a brutal slugfest, and not for the feint of heart.
All that being said there is a time and a place for this type of balling, I suppose. As long as player can ensure he isn't overshooting individuals, is letting shot players out, can hear ref's instructions etc...
It certainly isn't my cup of tea, at least my style. I will play against it at events like castle without batting an eye - I could give a f*** - thanks for letting me know where you are on the field at least... lol.
I prefer a nice day of rec-ball anyday.
