I have made almost now 2-3 armies per Sub Faction at 2k and they all mostly float around 95 Power.
Power for all intents and purposes is basically 1 Power = 21.05 Points. I do not understand why they added effectively the same mechanic as points other than they just wanted an easier for new comers to come to a table without spending hours thinking about the best way to maximize their units.
Any comp based on Power is just simply dumb.
Any comp in 8th is dumb plain and simple. The WHOLE point of the revamped edition changes is they will have have a yearly cadence release of updated point values to units to keep the playing field "balanced".
Comp is dead long live 8th.
