Warlock always had the ability at this patch level/design to cast a Powerless/UI/Range Ex and then have up to 10 seconds to cast a secondary. It's currently bugged to require you to select your secondary spell while the primary is casting and although that's correct for the cusring baseline bolt/dd spell it's not correct for the primary UI/Range Ex/Powerless primers.

Casting powerless/ui/range ex should have 10 seconds to cast a lifetap/pbaoe/snare/ns/etc

It allowed warlocks to avoid LoS slips and have tech options.

https://youtu.be/slQNoi2iqWY?feature=shared&t=377 is a solid representation of how it should work... you can see me cast the powerless.. hold the secondary spell until the enemy comes into line of sight and then drop a secondary+chamber on the target. Granted that video is during the 2 chamber era of warlock and on mordred the ways the primary ui/powerless/range ex spells worked was the same for those abilities through all versions of the class.

Even if for balance sake you guys don't want the 10 second ability to hold spells it should be 5 at the minimum and making the secondary spell need to be used while the primary is casting is a bug.

Furthermore, you can see at 6:47 in that video where his combat log says "You move and break your modification spell." in case his prior example was too quick.

This is how we chose to design it.

The breaking on move was also a thing on live.
