Game in standard league rendered unplayable after Phrecia update?

Aprox after Phrecia update, the game started stuttering in hideout, sometimes 20 or more seconds not responding. The maps were almost ok until yesterday, when they became unplayable also. Seems like in morning hours (european servers) it is better , almost ok, and the issue starts afternoon.
Is it a common issue with some plans to solve, or it is happening with every update or new league start?
Issue: game regurarly stops responding, with active effects(flask balls f.e.)frozen, and after some time it catches up with all missed activity done in rapid speed. Sometimes iam able to move, just the game does not react for actions like stash opening, map opening, item manipulation .
I tested my ping check, the results weve very good, i dunno what to change to continue to play the game. In curent state it is unplayable.
