Snip
Its not either too many without or forced commander picks, its both. I hold my commander pick specifically to ensure arty as allies. Because no artillery, players must hold their picks.
Thats why Axis players really hate SPGs, even though they are in only 1 commander per faction. They end up required. Calliope is in only 2 commanders, but in every 4v4 game with USF for the same reason. It massively stagnates commander pick rates.
Turns out this applies to Axis as well. SHTDs solve Axis's single biggest issue: heavy tank destroyers shutting down Axis armor. Jadgtiger and Elephant shut down heavy tank destroyers. Breakthrough and Jaegar Armor are both top picks for this reason. ISU-152 spam was a direct response to this by sniping units from under the SHTD protection envelope without any response.
For some reason, all of these commanders are also some of the best designed and heavily loaded ones in CoH. USF Infantry currently has the only consistent howitzer kill off-map in USF, on a commander with the best anti-howitzer unit in the game, the Priest. JA has self-spotting and a cheesy off-map AT. Breakthrough has Sector Assault and its HE barrage, letting it hammer infantry while still maintaining its AT envelope.
A fix generally is make the commanders that DON'T have these mandatory tools strong enough to compensate (heavy tank meta, new Rifle company) or make these dominating doctrines straight weaker (as discussed). We are seeing this now with the nerfs to ISU-152 so SHTDs can snipe it, removal of howitzer control from JA and ISU doctrines, removal of spotting scopes from JA. Someone mentioned nerfing Sector Assault on Breakthrough, and I would add nerfing HE barrage on the Jadgtiger. This would make paradigm breaking commanders dramatically weaker, as it should.
The other necessary fix is to give proper shock indirect to the factions that don't have it. All tools for all factions. Calliope and Land Mattress would be made non-doc and adjusted for proper shock artillery statistics. USF had the Pack Howi and Scott for that job previously, but the change to focus on barraging means they can't consistently punish infantry blobs just team weapons, so they need actual shock arty. UKF has had issues literally since release.
