I suppose it's fun to someone who is good at it, but I'm not a real team player.
Everyone uses Force Speed in that game and it gets me hella confused. It also takes very long to kill someone in basejk.
But the most annoying thing is when you grab the enemy flag, you can't cap it because the other team has yours.
So you're yelling at your team to kill the flag carrier while being chased by your opponents for your flag...
...Don't let my opinion stop you from creating a fun CTF server
PS: Get JK++ mod, since it makes damage and force higher and faster to kill.
