- Which stun? Lucille having no true lockdown is one of her main weaknesses as a support.

- Static Field is a delayed "skillshot" (like Nevermove). Lucille's cast times should be ~0.25 second with 0.5 second for DEM for balancing purposes.

- 3 seconds is reduced to 2 seconds by Mercs. Removed by Cleanse/QSS. Having a 90 second CD with 40% CDR. Having a 0.5 second delay that allows you to cast your escape/disengage abilities (like Gragas ult) before being silenced. IMO that's not broken.

Although I agree that DEM has a problem: it 100% counters Shen and Karthus since their ultimate have higher CD and require a channel. I would like to solve this problem but I don't know how. Increasing the CD even more would make the ability worthless early game (it is already one of the worst support ultimates for the laning phase in fact, it is only strong for teamfights).

I thought about: Delay reduced to 0.25 second, applies a debuff for 2/3/4 seconds, if a debuffed enemy casts a spell, they are silenced for 2 seconds. This way, you can't cast a channel DURING DEM (it will be instantly interrupted) but any channel cast BEFORE DEM will not be interrupted. However, this allows enemies to freely use Flash (not an ability = no silence), while the main purpose of this ability is to prevent Flashing out of the E.
