That is absolutely brilliant!
The guys I play with seem to think that the GW point system is infallible and didn't take too kindly to me questioning what possible algorithm is used to balance. A consistent formula that produced measurable points.
I agree with you both, and I love how you managed to evolve that scenario.
"Is it fun?" should be the most important question, and I openly told my gaming group that I really genuinely didn't enjoy it.
I enjoyed it when we were playing open play, and if at any point one player felt over-whelmed or out matched then there was a reinforcement allowance. "If things feel unbalanced, then you can bring a unit of xxx on".
I played 8th for years with Woodies, and enjoyed it. Never super competitive. My favourite model is Orion so I want him in a list attitude, but won games ...or at least had the chance of winning.
Using any amount of points of my woodelves can not compete with a Frostlord on a stonehorn AND a huskard on thundertusk. They wipe my army out in a matter of 2 turns everytime. I liked how you made eliminating the opponents army detrimental to the objective of the game.
