Unbound ultimate collection

Is Unbound ultimate collection worth its discounted price even tho I would not play it as aggressive grinding like these CODs and battlefield thingys?? I saw the contents and think I would just like to have it if there ain't another sale happenin'/ happens at a later date when I won't be able/aware to purchase...

Or will there be a bigger sale where they expand ultimate collection?? And the price will be nearabout the same??
