1st round both teams start in the field outside the castle doing open battle.The winners then move into the castle to defend the other team goes offense.
Then instead of 1 flag maybe have some points of conflict where you win the point your team spawns there and each point gets progressively closer to the final flag.
To me this would give it more of a sense of progression rather than the run to the flag die try to run there again etc.
Might not work in some of the smaller maps but it would seem like it would in the larger ones like the one everyone QQ's over the long walk to the castle and some other larger ones.
Anyways just a thought,maybe not a good one but hey you never know.Any thoughts or opinions are more than welcome.
