New to Halo; Quick few questions

While Halo 5 has been out a bit I decided not to buy it until the other day due to getting bored of my other games and I have just a few questions that I couldn’t seem to find listed anywhere so if any help would be appreciated,

First Q: Whats this ban system? After my first night of playing, mostly griffball, I played a solid 10-15 games and a couple hours into the game got kicked for “greifing teamates” and while it was a complete accident (as many of you know how Griffball works) I understood being kicked, but then it was followed up for a 15 minute ban which seemed a little rough but oh well its 15 minutes. Then on my second day, yesterday, I was kicked out of two games out of the 30 I played and was banned for 2 hours, once again the times i get kicked are complete accidents where im simply trying to defend the goal and hit a teammate in the process. After this i just switched games because its a little ridiculous to wait that long for no reason, so if someone could just help me understand the banning system, does the ban time keep rising every time, does it restart ect.

Second Q: Are the only thing to use the REQ points (Might be the wrong term) on is packs? If not how else can you use them and is Armour/Unlocks only available in packs or is there another way?

Last Q: I see a lot of chatter about an upcoming update this month but cant find any date associated with it, is there one or is it just sometime randomly this month?

Thanks to any responses

Q1: Yep there is a pretty intense banning system, basically if you leave a game for any reason (kicked, betraying, lost connection, etc) then you can get banned
Q2: You only use req points on packs and packs will give two permanent unlocks each (unless its bronze which gives 1 per pack) and a permanent unlock is armor, emblems, stances, assassinations, visors, etc.
Q3: The update coming up is Memories of reach and it was just recently pushed back to May and official dates are coming soon according to Bravo.

1Q. Not sure of the ban system, haven’t been banned yet.
2Q. You can only us req points on to purchase req packs. And sadly, yes, you can only get armor and permanent unlocks from the req packs. Oh, and for completeing commendations, but those too come in packs.
3Q. There are monthly updates, 343 usually posts when they are releasing the updates.

The more frequently you quit or are kicked from match for whatever reason (betraying/inactivity), the more severe each subsequent ban will become. As you go through longer stretches of games without quitting or being kicked, your potential ban lengths and frequency will also decrease.

Grifball shouldn’t have betrayal kicking, IMO…

Is there anyway to “appeal”, in a sense, a ban? Playing grifball for several hours its almost impossible not to accidently betray. Is there anyway you can have a ban revoked or looked into so they realize it was an accident?

There is no appeal process.
