To be honest, I don’t think the towers will be all that useful. The distribution of colors is almost identical on each side of the field, and the cubes are mixed together, so teams are probably not going to specifically go after a certain color - it’s much faster to pick up a big pile of cubes of various colors all at once than to try and pick through each color individually. Also, if teams have a stack with a pretty even breakdown of colors (about 1/3 each color), then the opposing alliance putting any cube in a tower would still benefit them. I feel like it’ll be just like how caps were in Turning Point - teams will ignore them completely.
(In skills, on the other hand, the “color doesn’t matter” rule means that towers will probably be the most important game element, as any cube scored in a tower will increase the score of all stacked cubes.)
I think the meta will be fast and tall stackers only that stack with no regard for color, and tower-specific scoring mechanisms will be practically nonexistent, especially towards late season.
