[GAMEPLAY] Lucian's E is being disabled for longer than his Q's cast time

When Lucian casts his Q, the Q and the E are disabled for the duration of the cast time. Before patch 7.5, the cast time for his Q was 0.4 second at all levels and ranks. Now, it scales down with levels, going from 0.4 second at level 1 to 0.25 second at level 18.

Though, it seems the time his E is disabled after casting his Q is still 0.4 second at all levels, as shown in the video I linked.

The video shows that:

1. At level 2, his E is disabled almost the same amount of time than the Q (0.39 for Q, 0.4 for E)
2. At level 10, his E is disabled for longer than his Q (0.32 for Q, 0.4 for E)
3. At level 18, his E is disabled for way longer than his Q (0.25 for Q, 0.4 for E)

The fact you cannot cast E immediately after your Q's cast time later in the game feels a little clunky. I hope I explained it well enough!
