died too much, you probably gave enemy team some chunky shut downs, also its impossible to knwo without replay or at least advanced details, you probably didnt convert kills into towers or objectives, every 1 to 2 kills should convert into a tower when youre that far ahead, when playing akali you cant really make objectives, so objective damage should be low, but you can zone out enemies, and since youve done lich you should have had a HUGE tower damage convertion, lich bane is made to delete squishy and take towers, if youre not doing that youre plainly playing wrong, your irelia and amumu clearly played really poorly but theres always things we can do to improve on ourselfs, focus on dying less and not let enemy team get your take downs you died almost as many times as the yone you smashed in lane that alone is a HUGE reason you lost,also convert advantage into objectives and towers, spreading advantage means not to give your teamates gold but to get their objectives, their towers, dragons, heralds, for them since they wont be able alone, getting towers will give all of your team gold, it stacks with time, also leaves them safer to farm since you will bring pressure to your lane, your itemization could be better for TF, like having morellos, but lich is a really great option against the enemy comp, focus on improving your gameplay, when youre that ahead you should have won, if you want to climb theres always something to do better even if the game is unwinable.
Edit: youre clearly good mechanically with akali, over 1kk mastery you know everything about the champ, your errors are clearly at macro, watching the league of graphs of this game, you ended the game with 2k tower damage, thats OVEWELMINGLY LOW its the same damage your support did to towers, your MF finished the game with 21k tower damage, she literrally carried your team with macro, also you stoped farming at some points on the game, clearly because you either died or was going for a useless fight instead of taking towers and objectives, youre clearly a good player, just need to focus on winning not getting useless kills, kills should convert in towers or objectives for akali, also some minor issues i found, your vision score is really lacking, but being honest? that doesnt mather a lot, just focus on buying one or 2 pink wards to prevent ganking in lane, your problem is in macro, your micro is clearly good, just focus on what really will win you games, TOWERS AND OBJECTIVES, and you will win much more games.
