Tried the 4 Teams Mode... yeah the win condition wasn't thought out at all. You might as well create 4 Team Deathmatch with mercenaries and replace the current 4T with that.
Let's try to look at it this way: how can we determine which team was the best? Well, capping all 4 point surely proves the best team, yes, but that team would be the best at being <span style="font-style: italic;">the most dense - as other teams just got tired and gave up, realising that this is pointless, as for each team it takes barely any skill to defend their own point(which, in a case of at least one map, is right in front of their spawn!).</span>
So, this surely doesn't work. There must be some other way of figuring out which team was the best without making it impossible.
For example: how about doing it more directly? Why can't it be the similar way as in KOTH mode in tf2? The win condition there is for a team to have the point in a captured state for a required time, the winner is the one to do it first. Well, that's just one point to capture tho, now we have 4... then how about a captured point instead of decreasing the time required - instead, it gives a point(score) per second. And if you have two points captured - the score you get per second doubles(2 score points per second). Or we go back to decreasing the numbers and the captured points act the same way as in KOTH: one captured point makes the team timer go down the usual way(1 second per 1 real second), but two points captured make it go twice faster - (2 seconds per 1 real second). And so on. Since in original KOTH the timer is 3 minutes and in tf2c we have double the teams, the timer could be 6 minutes. If a team captures all 4 points, then the round ends in 90 seconds. A bit too fast... maybe 9 minutes.
So there's whole two ways to script this. In a game, if you manage to capture someones point(and <span style="font-style: italic;">it is "someones" if it's right in front of their spawn) and keep your own point defended, then good for your team - you're now a little bit ahead from other teams. A "little bit" because the point is not too hard to capture back if it's right in front of your spawn(I keep saying that, am I?)... Sounds playable to me. Also doesn't seem to be too hard to understand for a new player.</span>
If no one responds to this in the next ~24 hours, then I'm gonna link my posts in the facepunch thread. Or just repost this one post.
