The capture the flag areas are not where they seem to be
Often you have to stand in a specific place to win in TO. For example, at the first stage of "Regicide at Trayan Citadel".
In such cases, you will see +10 points if you stand in the area pop up every second or so.
Many player rush through these areas, if the enemy is still further away, this is a mistake. If you do stand inside the area, and prevent enemies from being there, you get points for the objective. If you rush through you do not. This is especially important at bridges, where you do not need to take the entire bridge, you just need to take the area in front of where the bridge ends, making it much easier. At bridge town, for example, you need as attacker, not take the bridge at all, just the area in front. At Falmire, you need control of two areas on the bridge, both are somewhat in the middle.
This can safe a lot of time and it might even enable you to win stages which are very hard to do, like the first stage at trayan.
