Summoner Rift is just Dominion, URF, Nexus, Aram as one mode.
Instead of making the other modes available for the shorter game times, cause that was essentially what they and Twisted Treeline were made for, Riot has taken their most popular mode, Summoner Rift, which is the pentultimate of strategy and team based gameplay, and have turned it into another arena-objective game. There is no longer any difference betweem playing aram (minus the random parts), and Summoner Rift. The laning phase lasts for five minutes, then teamfights happen, whether for dragon or herald. And the first person to win that first fight will likely take a turret. If a team gives up an objective for safety, the other team now has more power. If its herald, gg a turret. If it's a dragon, the pain is lessened but they still have a better advantage. The next dragon happens in five minutes. Be ready to fight or lose that dragon again.
Summoner Rift as a mode is no longer about strategy. It's about 15 minute gameplay, then spending the remaining 10 waving at the victory line. If you wanted a strategy game with such pace, Riot, you should have invested more time into Twisted Treeline. Considering SR became your most popular mode, though dominion was technically an easy second, instead of accepting that your players loved the way things were, you decided to hop on the URF train and push games to be immediate fight fests. And because of your model of releasing new champs, you'll always have the problem of a lot of champions being worse versions of the new ones and then having to repeat the endless cycle of reworks.
Your game has been destroyed by maintaining this vision for hard, fast cash. And you're suffering for it now. If you were smart, the best way to go about this would have been to keep Summoner Rift as it was and maintaining a second mode toward your vision. We thought Nexus was suppose to be this, but it seems whoever is calling the shots is asking that everything about league has to be a 15 minute burst fest with no strategy involved.
