War victory crystal

I just got a 3 star arena boost upon opening the war victory crystal. Quite underwhelming. I think this crystal needs to get buffed. Is this possibly the worst reward payout in game ?

I doubt if this is anywhere on their list of priorities. I think if they thought this was important they would have addressed it when they added seasonal rewards to the game. If I had to bet money, I would bet that solo crystals get updated before war victory crystals do.
I doubt anyone posting in this thread has every 3-star and 4-star signature ability maxed out.
So unless that is the case you can definitely progress your account from these crystals.
I'm happy when I get loyalty from them lol. Usually get ISO or a L1 alliance health potion.
I have never use them, don't know how to use either.
