You see a similar bad attitude on the forum, usually by people defending things like rockets (though they always say that they only 'sometimes' use them). Coincidence I'm sure.
The thing is that they won't even care if they get nerfed - they'll just leave the game and go play something else.
I assure you I'm in for the foreseeable future. My guess is the next time we see anything like this is around 2028.
First of all, Eugen needs to fix the artillery bugs. Until that's done balancing is useless. More info here:viewtopic.php?f=14&t=3469
Next, most people really do play terribly. You can't balance the game to please people who don't know how to play.
Next, they need to make the pricing internally consistent. There are some units that are so much better than others that it makes all other choices obsolete. This may or may not change when bugs gets fixed: we'd need to reassess the thing then.
Next, if and when we get new victory modes Eugen needs to decide whether they want to balance for one certain game type or some sort of their own vision of what the game should be. If units were free and you'd play command post hunt, would artillery still be overpowered? More info about upcoming changes here:viewtopic.php?f=4&t=3470
And after that, if artillery is still too dominant then Eugen needs to start working on whatever the balance issue is. I have a hunch most of the arty hate springs from three things:
1) bugs (pinpoint accuracy, unintuitive impact patterns, ROF bug, possibly morale)
2) wrong mental model of how the game plays
3) relative expense of the units people want to use, and the effectiveness of artillery against these particular targets (top-end tanks, large-ish groups of tanks). You only get a few of these expensive toys on the field and they're easily wrecked by especially artillery as it now stands.
I'm very interested in hearing your analysis what the game would and should be like after the bugs are fixed and average level of play is reasonable.
