FPS drops since season 29

My game was perfectly running on 240 fps during 2 year. But when the new season came, i have in every game fps drop running low like it feels 100 are less. Its happens with Axle being near using her spells are when there is too much people are fights... I dont know what the game did with the optimisation but it kills the gameplay, and its not from my pc cause i didnt do anything in the settings, im updated on my pilots... 

So if people have the same issue since the new seaon, do we have to wait after EA to optimise there game ?
