Melee Casting Questions

[Ikonoclastia]

Hi, been doing some searching of posts but unable to find the correct info:

Prior to velious, casting during swings would reset swing timer, however from researching here that was not implemented when this server first came up and swings would wait till straight after casting finished and not result in a swing loss? Is that still the case?

If so, and swings don't reset, if my weapon has a delay of 24 and my spell has a cast time of 1.8 how do I figure out if it'll fit between swings, or is 1.8 1.8 seconds and 24 2.4 seconds?

I'm thinking of getting rid of this silver swiftblade and getting something much slower so should I give up casting until I do that?

Apologies if this is basic common knowledge, I only had one melee on live and I twinked and PL her so no idea about melee.

Thanks
