1. Ban should be atleast 8-12 hours, a whole day is pretty harsh for somebody like me waiting for it to go away. 

A shorter ban duration would not work. The result is inconsistent punishments and a higher frequency of leaving when bans won't bother them (late at night).

Let's use a 12 hour ban as an example.

Hypothetical situations:
A: Someone leaves at 11AM but wants to play later on in the day.
B: Someone leaves to sleep at 11PM and wants to play later on tomorrow.

Outcomes:
A: Severely inconvenienced. The ban expires around the time they would head off to sleep (11PM).
B: Barely inconvenienced, if at all. The ban expires in the morning (11AM), which is not too long after waking. The ban is definitely gone by the time they come back from school or work.

2. "No sub in 2 mins" should be increased, It should be 5 mins to give players some leg room to maybe restart their PC, Internet or getting somebody else to sub for them.

Two minutes means your team potentially plays 4v5 for 1 to 3 rounds. Five minutes means up to 8 rounds played 4v5. I don't think your team is going to be happy about that.  

.need/nneed should be triggered immediately if a player joins a PUG server.

That would cause too much spam. In general, I don't want to hammer the group with announcements unless there's a good chance of the PUG happening. That's why .need doesn't begin to automatically occur until there are 5+ players. Also, what if they are planning some kind of in-house PUG/scrim?
