Loot pull garbage

I think you guys really need to consider throwing people a bone once in a while. I grind out every event to earn loot coins or the gold chest and just get nothing everytime. I don't know why I grind these fueds anymore because my "guaranteed mega pull" from the 7 loot coins was a card that's been givin away at least twice. It's just getting tiring and I'm realizing I'm doing this all for nothing. Grinding should be rewarding but only the people with big wallets get rewarded.
