What’s the best playlist in your opinion to get perfection? It used to be big team infinity slayer but ever since June 3rd… the playlist has been a mess for me. Bad bad mess. So I don’t know where to get my last two…
I’ve got my first perfection in BTB so i highly recommend that playlist, its where my most perfection are done 
Read what I said. I used to do it there… but now…
Yes i read that BTB isn’t your option at the moment but IMO its the best choice.
Other playlist i got one perfection was Team Doubles. If you get a well skilled teammate, you could easily get perfection in Doubles 
If they don’t quit. I think the penalty should be harsher for quitting, and make players know. I could have potentially have had all my perfections if it wasn’t due to quitters.
Ragnarok and daybreak seem best. Shatter too on mantis but… I don’t get a lot of shatter slayer.
Oh, and swat is kinda easy as well. I remember in reach i got probably a couple ones. In halo 4 i can’t remember if i got any… But BTB is still the best choice 
one little thing that pisses me off is that there is no longer a perfection medal, or a sniper headshot medal, for some reason this bothers me alot anyone else?
Definitely BTB. I have roughly 20 perfections (Since I can’t tell the exact number) but I know for a fact I have over 50 Running Riots.
The easiest way to get perfections is to play lesser skilled players (obviously. Stay with me here). This can be a challenge with the CSR matching system matching you with players of similar or better skill (yet when you want to play people of similar skill, you are matched with crappy teammates and opponents).
Looking at your service record, your clearly a good player with a pretty solid CSR in every playlist that you can play slayer in par Swat and Snipers. I wouldn’t recommend even attempting perfections in them playlists. Your best bet is probably Team Doubles. You may spend hours looking for scrubs but when you find crappy opponents, its almost and instant perfection with a decent teammate.
My first perfection was in Team doubles (20-0) and my second didn’t count as my opponents both quit as soon as I hit the running riot. I have had plenty of games going about 17-1. As long as your opponents primary weapons are sticky grenades (what always ends up screwing me over), your good to go. Just remember to use Regeneration field and always time the weapon spawns. The Railgun is a guaranteed 3-4 kills.
The perfection commendation is just so stupid. If you ask me any legendary medal (killionaire, extrems, Unfrigs) should be all one commendation.
THe fastest way to get a perfection is to play infinity slayer in the crimson dlc playlist. I got 1 perfection yesterday.
I do have to say Big team slayer too, especially on ragnarok since on either side you can just hang back with the sniper, just gotta be careful and stick to cover.
How many perfections until you master it? The few times I set out to earn one (in BTB) I’d get to ~12 kills and then get tanked/banshee’d/found out.
I tip my hat to anyone who has earned even one!
I would suggest getting a decent partner and running some Dubs. There is a lot less chaos with only 4 ppl in the game. I have 1 perfection so far and almost got my second last week (both in Doubles).
