1 : Its impossible to move the middle game-Announcements, just suggest it, but it was already before
2: Every base-cristal-augments just changes a mechanic of turret, but not relevant status, harpon is for those who dont want to math the patch to the enemy, so just press space like a railgun and go in straight line

Who have more points of difference score more points on scoreboard
For example Blue have 3 captured points and Red 4
Red has +1 of advantage, so the points of red team will increase each 13 seconds(i think its this number)
For each 1 additional point of difference of advantage, the timer to count one more point is decreased by -3 or -4 seconds, so that means that if your team have 3 points of difference, you will need like 6 seconds to score one more point on scoreboard
Also if the winning team, like 23 vs 43 (total of score of each team) ,if the team with 23 points cap more points in the game,the team with 43 points will decrease their score -1 from 43 to 42 while the team with 23 increase by +1 from 23 to 24 and so on
The mini-game is for teamwork like siege, you cannot win that alone
