Smaller pulls give more leeway for the unexpected like the healers kid irl suddenly screaming like they're being killed in another room or someones dogs going berserk... doorbells and phones ring... you're less likely to wipe in a smaller pulls when real life comes crashing in... remember you're playing with real people with their own real lives... 10 mins longer isn't going to hurt anyone and if you really feel it is perhaps you need to take a step back from games for awhile...
