Is it just me or are cooldown timers wonky?

Was on R50 Archer and when i use multishot it counts down from 10.(in 1.18 it was 15seconds) But i will only be able to use it 2-3 seconds after timer ends.

Seems to be similar across all skills. >< noticed approximately 5 seconds missing on all timers?

Kinda irritating when you hit skills and nothing happens.
