A entirely new mechanic: a general for the parliament. A general that the alliances chooses and upgrades together using rubies. This general would be far stronger than the others and provide buffs to the buildings/troops around it. The buffs would be chosen by the alliances leader and everyone will contribute to the buffs via rubies.
The buffs would be aoe based and only last as long as the general is alive . The buffs would be very similar to the manufacturer buffs. They would be all unlocked in the parliament and it could be that there are different generals you can choose from. Each one would provide buffs according to their style . A general who focuses on troop buffs, or building buffs or tactics . No general can do all.
The generals buff would swap roles once on defense or offense ( on attack provides 10% damage buff to units in aoe, on defense provides -10% to enemies)
This would finally put some use to those extra rubies .
