The only good thing there are the SSR ticket (3000 gold)
Elixers so you can farm more and help you to level up (100*25= 2500) and energy leaf so you can join more raid/union battles (100*25= 2500)
So the price of those stuff together is indeed 8k, and the other stuff...find them unworthy
At my current pointvin the game i wouldn't buy it and just get the SSR draw or wait for miracle/restock of ssr ticket rather than buying it, but it's up to you.
1 more thing, energy leaf will give you 5 bp, while elixer the amount of your max AP (or revive if you got beaten)
So for a new player with low ap you will get lower ap from it compared to players thayed for longer
