SpriteI think the idea of adding more maps is a good idea but they need to be added overtime, putting 5 new maps into the rotation next season would be stupid, teams would have to create a new "meta" for how to play the map 5 times over and whilst it sounds good in theory "oh we'll get interesting strats and things people didn't consider" really it'll just be a DM shitfest where people aren't quite sure what to do as we saw in the livestreamed cup
personally i think this is a lame cop out.
The teams that wont care to go over the maps or try to make strats for it are the ones that will try to turn it into a dm shitfest and will be the ones that eventually lose to another team who took the time to figure the map out and learn the holds, best mids, etc. Also literally nothing what you said changes the "meta" of the game, that's done within the balancing of the classes, weapon bans and what people find strong etc. The maps don't change the meta. there are meta's within certain maps but those are entirely different and don't reflect the overall metagame
I used the word meta because I couldn't think of a better word for it, I mean like how people play on the map, positions, strats etc (basically what you mentioned) but if you put 5 new maps in on the same season it would be a shitfest for a while until people really figured out things that work
look at like gullywash when that was added and the strat used to be bomb your entire team onto them at big door and everyone pushes under and people would run heavy and sniper to mid, then think that's what each map is gonna be like bar a couple of teams who try really hard, these things take time (even take a look at like reckoner in EU map pool the map is constantly being edited and changed because people don't like aspects of the map and people are still unsure how to play the map to its full potential)
adding new maps is a good idea and there is a clear desire from players for new maps (look at the thread about rating the current map pools, there is a reason there is differences in the ratings and that's differences in opinion about each map) but to cut out so many classic maps in a single season i'd imagine wouldn't be recieved very well by the community.
That doesn't mean no new maps should be added, maybe like an actual voting system at the end of seasons to judge how they liked the map pool or something or a few different ways to trial different maps idk, just some ideas. Some of the maps in the mapcups did look like they had potential to be solid maps in the rotation.
