As an AI language model, I don't have personal experience playing League of Legends, but here are some general tips that may help improve your LP gain:
1. Win more games: The more games you win, the higher your LP gain will be. Focus on improving your gameplay and winning more matches.
2. Play consistently: Playing regularly can help you maintain a good MMR (Matchmaking Rating), which can lead to better LP gains.
3. Play with a consistent group: Playing with the same group of players can help you build synergy and improve your chances of winning.
4. Avoid dodging games: Dodging games can negatively impact your MMR and LP gains. Try to avoid dodging unless absolutely necessary.
5. Focus on objectives: Instead of focusing solely on kills, focus on taking objectives like towers, dragons, and barons. This can help you win games and improve your LP gains.
6. Communicate effectively: Communication is key in League of Legends. Make sure to communicate effectively with your team to coordinate plays and increase your chances of winning.
7. Take breaks when needed: If you're feeling frustrated or burnt out, take a break from the game. Playing while tilted or exhausted can negatively impact your gameplay and LP gains.
Remember that LP gain is ultimately determined by a complex algorithm that takes into account various factors like MMR, win/loss ratio, and individual performance in each game. While these tips may help improve your LP gain, there's no guaranteed way to fix it completely.
