Convergence and Anomaly are the 2 worst maps for 6v6 and should be dcv
Convergence is a straight line with no flank routes, and if 1 team is even slightly stronger than the other your cornered for most the game.
Anomaly is way too small for 6v6, it tight corridors and open central area make it way too easy to pin down one team if the other is again only slightly stronger. Also since it's so small, there is limited flanking routes.
Convergence is a balanced 3 lane map.
Everyone just seems to forget about the bottom lane, and decides to hardscope top lane lol.
Mid lane is also fairly safe as long as you maintain high positioning. Unless someone is holding the top cube angle, you'll be completely safe. If someone is holding that; double back and hit the out route to bottom lane where literally no one ever goes.
