In the game rules or appendix somewhere, they mention that a typical Art unit in CoG:EE is about 100 guns. It's abstracted of course, just as 10,000 troops doesn't actually translate to 10,000 infantry (or Cavalry).
I've had concerns about the devastating power of Art as well. If you acquire all Art Upgrades, at Division level battles you can kill 4,000 men in a single shot.
Although I've played CoG1 since 2005 and actively play and play-test CoG:EE, I only recently started playing my detailed battles at Brigade level. While it can still be fairly devastating at Brigade level, the modifiers for off-axis attacks coupled with Art being more vulnerable at Brigade level and the ratio of units (Art only split into 1 Brigade, while Cav = 2 and Inf = 3) changing, I think it works perfectly at Brigade level.
In summary, Art might be a bit over-powered at Divisional level, especially after you acquire numerous Art Upgrades (especially Art ranging, which should be, IMO, reduced to 1 hex range change at Division level). But it should remain the major factor on the battlefield, as my reading of the period confirms. Rarely was it not a decisive element of battle.
I've been missing out - Brigade level battles are awesome, feel much more "Napoleonic" and grand in scope, allow for more tactical choices, and require more hard work and thinking. I doubt I'll ever play at Division level again.
