Points need fixing e.g. skaven cannons, TK knights, TK tomb swarms, (and any similar that can appear from off the table and easily grab an objective but are very cheap), vamp on zombie dragon, some bloodbound, warrior brotherhood stormcast battalion, big killer units of ork type archers, etc to name a few. Needs some meaty changes in places.
How about units not being able to claim objectives in the turn they come on the table ( this was in one of the previous comps widely used and made this type of unit require a level of skill to use)?
And I agree that shooting in and out of combat needs fixing to make it feel " realistic" (in a fantasy game, but you know what I mean!) and nerf big shooting units in favour of close combat.
Measure base to base.
Keep priority roll but like Lord of Rings game, if a draw on dice roll it goes to the player who did not go last.
Clarify when spells and other abilities impact the unit/model pushing them out more clearly.
More variety in pitched battles so not all objective based.
Balance Allegiance abilities more Order one is very weak.
