for the sake of esports you should stop drastically changing the game.
first of all there is a flawed reasoning behind why the game is being constantly changed.
the idea is that by changing it we keep it from getting stale.by adding random dragons, and plants, and mini games to champion kits.
the issue here is that this game cant get stale. its too complex. and each individual match is completely different from the next and previous. poker is played with a deck of 52 cards, and it is said that to this day there have not been enough poker games in the world to actually see every hand possible. meanwhile we have 133 champions, there have definitely have not been enough games played to see every possible combination.
now im not saying dont nerf and buff champions, or even change some of their skills around. no, thats not what im saying, im saying dont add or substract from the basics anymore. seriously. dont. dont change dragon types, add clunky jungle mechanics for no reason, and so on. in season 3 you had the basics of the game down already. it was all established, you just had to better balance champions and release new balanced champions and keep it that way.
now this doesnt really matter to your average bronzie, but for esports its hugely important. you cant play a sport and practice and get better at it when you have no idea what the rules of the sport will be next year. and how they might change completely to not even be remotely similar to what it is.
theres a reason why there are no major changes in football, soccer, tennis, basketball or baseball or any other sport. major changes confuse the audience, and impede the talent of the players.
the best way to make this game more interesting isnt through silly niche mechanics and mini games, its through better balancing of champions so the players show more champion pool diversity and therefore make the game more unpredictable.
