The Ability to Ready a Spell While Casting - Why Was It Removed?

[Razzle]

Hi,

I'm sorry for my English it's not my native language.

I'm sure it's not as big problem for most of you as it is for me and mostly mage classes, but since I play Conjurer mainly, and the removal of this feature affected me greatly, I decided to make a post about it.

The feature which lets you ready the next spell while casting another, was removed in patch 1.19.
Being able to "register" a spell let me react fast during raids and commit party plans with much more precise timing.

Since my connection and how far I live from the server, I have some delays commiting actions. The ability to ready spells beforehand, help me bypass slow latency issues like those.

Let me explain in actual details: When I cast a spell, my casting bar gets to 100% and stay there for 4 seconds (because of lag issue) before the spell happens. Of course that's a latency issue on my side, but the point is that Pre 1.19, I was able to bypass that issue because my next spell would register and start it's cast while I see that 100% full casting bar delay on my screen, and then the animations would catch up.
Right now I have to wait the 4 second 100% casting bar on each spell I cast, making buffing alone take much longer!

tl, dr: The big question is why was this feature removed? I never saw anyone annoyed by this and can't think of anything that would make SE remove this... This feature was very useful for me and made my gameplay much more fluid even in lag times. Is it possible to put back? What are the plans about it?

I hope the developer can reply about it,
Thank you.
