More along the lines of the second option.
Most elements are ~10pts strong (regardless of whether you follow the scheme), at 35pts you get 3 elements; this leads to easily imbalanced ratios:
- an opponent with all infantry aside from either one jack element or jack 'support' leads to a very infantry heavy list that is hard to counter with your own 3 elements
- an opponent all jacks aside from support leads to a very jack heavy list that can be hard to counter with your own 3 elements
Similar inbalances occur with a focus on stealth, multiwound models, ranged models, infantry models, etc.
Below 35pts this isn't an issue as all lists are (more or less) themed and you expect imbalance; 35pts is considered a standard by many and the situation can be hidden in a balanced meta; at 50pts you have enough points to have elements that can directly counter these issues of balance.
It's all a part of the game - our tier lists directly exploit this imbalance.
