Discipline is OP if your whole team has it around ~60 or 70 with no checking.
But yeah I agree that hybrid hasn't been the greatest for the league, but it is a much much healthier solution. I think it's been unhealthy in the terms of player progression for welfare players, as you'll like never have a good player now whereas pre-hybrid you still could. Which can be argued whether it's good or bad (people contributing more content/work to the league should probably have better players, but should it be impossible for welfare players to have all-star players?).
I think one potential solution is just increasing ratio's by like 1.3x or something small. Would need to look into it more. In terms of build flexibility, it definitely allows for more flexible builds, but it locks people out of insanely off-meta builds (you can't ignore attributes). Wonder if we could allow TPA recalls to just target the STHS attribute instead of the hybrid attribute. Would need rules on it so you can't just recall all of your passing but might open up options.
