Im not sure if the prestige shop will be open from day 1. Some things fourzerotwo says is very misleading so we'll have to wait and see.

Whether it is unlocked or you have to wait to prestige once to unlock it, im going to not use any tokens from the get go. I will play through my 1st ranking normally. Use all the different weapons, equipment evenly to see what suites my needs. It would be foolish to unlock a bunch of guns from lvl 1 and they suck. Lol Plus its kind of fun to rank up normally with no advantage.

I will have 4 tokens .. and after I prestige the first time i'll have 5..

Prabally a custom class slot and possibly a high level gun.

Also keep in mind if you unlock a gun, what lvl you unlock it at. It would be dumb to unlock a lvl 20 something gun as you could reach that level quite quickly. I wouldn't unlock anything under 40ish..

I wouldn't think the 2xp would be worth it to use a token on..

Since it will only be for a 2 hour period.

Can't you just edit one of your 5 basic classes instead? With Elite you can supposedly edit them even while in-game. Not sure on the restrictions though

Victor charlieINTEL Victor @fourzerotwo @evlmnke11 I thought the prestige shop is unlocked at rank 80? So it's available "day 1" out of the box? 

Robert Bowling @fourzerotwo Robert Bowling @charlieINTEL @evlmnke11 Prestige Mode (the ability to prestige) is unlocked at 80, but if you have tokens already. The stores open. 

So there is your answer, if you have tokens, it is open immediately

The additional create a class unlocks are capped at 10, so you may need to rethink your 15 class strategy!!
