For me? No. I personally find it more fun to play when you can also protect the flag.
Maybe it's a rule that Admins and mods can enforce and keep an eye on and not permanent..
no camping at both your own flag and the flag of the enemy. I understand that it's hard to see when someone is protecting the flag or camping, but I still think the option to protect your flag should remain.
What I find more important is; no camping in the anemy spawn. So don't stay in the enemy's spawn to shoot players instead of going for the flag.
It's incredibly frustrating when you've just come back to life, to be shot by a camper who stays in a corner
