The official "answer" from the wiki:
While the exact territories and bonuses don’t have any strategic meaning, it’s advantageous to have a map instead of a simple list because it helps visualize how well clans are doing compared to others by seeing how big their circle is. It also makes it easier to visualize how much time is left in the season simply by how filled the map is.
...
Another advantage is that each season can be played on a different Warzone map. Sometimes you’re conquering the world, sometimes Europe, etc. In addition to your clan starting from a different part of the map each time, this helps make each season feel unique.
The problem with this is:
(A) no one actually uses the map, we just go to 5s's script; the map is literally useless, especially now that it even shows the games with links, there's 0 need to ever use the CW map interface; tbh it always sucked, way too many clicks to do simple things like see the leaderboard, figure out the gap between clans, see recent games, see player's games, etc
(B) the visualization was only ever ballpark, b/c territory sizes aren't all the same (there have been maps where MB/MH/Masters [whatever clan was leading at the time] had the most territories but took up very little space with several small territories compared to another clan with few but big territories, thus making the best ranked clans look less successful than the worst ranked clans), nor are they even necessarily clustered together (they are at the start of the season but as things progress, they can spread out and not be easy to understand; either way, even if you perfectly understood the territory counts, it still doesn't tell you who is winning when 2+ clans have same territory counts; TLDR: the visualization isn't effective, so you still end up having to look up the # of wins, at which point reread (A)
