Slight balanced problem here.

The key thing about victory flag is to not focus on it too much. But still make sure the enemy isnt allowed to dig in around it.
Just don't suicide rush the flag if you know your just gonna lose it a few secs later. (Unless they are close to reach 100% with it ofc)
Victory flag is more like a Combat game that prevents the enemy from hiding in a corner.

I agree that games that end up with a shitload of arty can be abit annoying. Tho there are ways to counter em. Either by getting your own arty or by trying to assault it.
