Yes please!
As it is right now most maps are pretty balanced when there are around 50-60 players on. However, if there are fewer than attackers tend to have an advantage, and if there are more, defenders have an advantage. This unfortunately means if there isn't right around that 50-60 player sweetspot, siege is really unbalanced and not terribly fun. It's especially an issue with low numbers, as quite often the maps become so unbalanced the server just dies.
