botmodeWhen it comes to maps, ESEA has 9 and ETF2L recently 9 as well. Nine maps is too many. Ascent, as a team, tries to get good practice on as many maps as possible and to cut it simply there are too many maps to practice. There are weeks when we don't play a map. There are weeks when we don't play two maps.
Having this many (or more) maps would not be a problem if that map pool was split into smaller ones for each seasonal season (esea and etf2l are 3 seasons per year) Spring season have core maps + propaganda/metalworks, summer season have core maps + sunshine/something else, and so on. And then each year, redefine what core maps are.
As a viewer, and as a lower level player who does not scrutinize every detail of play on a specific map but more on general 6s concepts, I enjoy watching and playing on shit as diverse as possible as it keeps the experience fresh, and I'm sure I'm not the only one. You gotta balance this (to keep viewers/masses interested in watching/playing) to your elite group needs.
Edit : coming somewhere with less practice than needed and adapting on the fly can also be a way to differenciate teams. For example on some motorsports the amount of practice at race tracks is restricted so sometimes teams step in the unknown. Therefore, if your team struggles to get enough practice on the whole map pool, so do your opponents.
