I doubt they accidentally left those unaddressed. I'm sure they felt those re-works would've been sufficient to boost us up to the level of a paladin. However, I do agree that those skills could use some thought, based on whether SE reduces the buffs already made.

It's true we could use a silence in our array, and your reason for it is to get rid of double bards set up in coil groups. That's a really good idea, but just take a second to consider groups who haven't been doing double bards and yet manage through coil turns 1&2. I know for sure my group has completed turn 2 without double bards at some point of time. The idea is the same for stuns, especially for turn 5.
