XP Boosts in Classic Helmet Pack

Sorry if this question has been asked before, but I’m curious if buying the Classic Helmet Pack for the XP boosts with REQ Points is worth it?

I already have all of the classic helmets, as well as every other Visual Customization REQ in the game. I’m curious if I’ll be refunded some REQ points like when I get 6,000 REQ points back in every Gold pack, or if I’m essentially spending 150,000 REQ points on a few Legendary XP boosts…

You get 9 Legendary Arena XP boosts and no REQ points back like you would in Gold packs. I feel like its best to just use any other XP boosts you have or open Gold packs until they decide to bring back the Legendary Arena/Warzone boost packs which give you 20 for the same price (I think its 20?). Either way its up to you, its not a bad idea if you have a ton of REQ points but I’m saving up until they bring them back.

I got about 7-10 Legendary Arena XP Boosts when I bought one. Not really worth it, if you ask me.

How long are these typically available before rotation? Just noticed the change from voice bundle.
