Is it worth bothering with frontline without OP premiums?

It's my first time participating in a frontline event and I expected it to be a good time considering how everyone says you can make lots of credits for it, but it's been a miserable experience for me with my "lower-grade" premiums like T-34-3 and T-103. I get around ~250k credits per frontline game after repairs and ammo. I guess it's an okay result, but I spend the entire match getting dickslapped by prog46, borasque and skoda t56 which isn't fun at all.. is it even worth playing this game mode if i don't have these overpowered premiums, or should i just go back to grinding credits in random battles?
