Buggo, over at the COH forums, has posted a topic asking what you think should be in the next COH patch (assuming they release the one they've been working on sometime soon).

This is perhaps your only chance to really voice what's wrong with the game and not being mentioned in the current patch notes.

The most mentioned things are the BAR and Calliope nerfs, making the Axis Grenadiers have better accuracy with their 'shreks vs Shermans, and implementing arranged team games for the 2v2 - 4v4 ranked matches.
