The required experience points to reach the maximum level in the MOBA League of Legends will soon be drastically reduced.
In a post on the official League of Legends forum, a player asked what the developers think about possibly adding extra experience points to the “First Win of the Day” bonus (a reward that gives double influence points for a win). This method would not make leveling up the account to the maximum level (30) too easy, but would significantly reduce the effort.
By the way, an account at level 30 is needed to start ranked games or to unlock all mastery points.
The surprising answer from RiotMeddler

The lead gameplay designer of League of Legends, RiotMeddler, gave an answer that most players did not expect. At Riot, various concepts for a better “experience” while leveling have already been developed. Ultimately, it was concluded that possibly in the next patch the total experience points required to reach level 30 will be halved.
This concept was already tested by RiotGames last year on the Russian servers of League of Legends, yielding positive results. The concept used has now been improved and will soon be implemented on the servers of all other regions. This change will make many players happy, as there has been a long-standing request to make the “grind” of experience points somehow more “pleasant”.
The impact of this change in League of Legends

“If you need fewer games to reach level 30, then you will also have less IP available at level 30. – And what about runes?”
- This issue has been considered. Through the permanent reduction (50%) of the costs for the typical Tier 3 runes, you should still be able to purchase your set. In addition, “fresh” level 30 accounts cannot start ranked games immediately because they likely lack the minimum number of champions required for those games.
“Shouldn’t certain summoner spells like Flash and Smite also be unlocked at earlier levels?”
- Riot is satisfied with the system of summoner spells and when they become available for accounts. Especially jungling is difficult for new players to understand, as they need to concentrate on mastering the individual lanes. Receiving Flash later is intended to keep the fast “power plays” that experienced players are more skilled at than new players out of the early game. The dominance of smurfs (i.e. second accounts) over new players in LoL is already significant enough without this summoner spell.
