European servers

But I do, and it's not only with dodging, things like using bane or fester right after using a DoT will cause the last DoT to not be spread/not be used for fester, or getting a skill cast interrupted for no reason (actually there is a reason: in the server side you're still casting the skill)

This happens to everyone, if you play summoner any at all, you know to wait a half second after your last dot to Bane or Fester, your dots are on the GCD, aetherflow abilities aren't, so if you hit with one before the GCD of your last dot is finished, that dot won't be applied.
