Hello!
Many of us want more complexity and more skills to use, but to do so we might need to free up space on our already packed hotkey bars.

So I propose that we remove some of our existing buttons!
We have one very clear example of a useless button in the:

"Summon Seraph"/"Consolation" pair. There are no circumstances where you could cast Consolation without also summoning Seraph, so there would be no loss if the first press of a new merged button summoned it, and the two subsequent presses used Consolation. No loss, all gain!

Now on to the more dubious and discussion-worthy buttons:

"Lucid Dreaming" - Everyone uses it on cooldown regardless of circumstances anyway, can't we just make it passive?

"Repose" - Does anyone ever use it?

"Ruin II" - This skill has somewhat lost its purpose, I am hesitant to propose removing even more damage tools but I don't really see why we couldn't just make the basic Ruin/Broil instant and replace this skill with something more fun to use.

"Emergency Tactics" - Potential passive instead? When galvanize fails or overwrite due to existing barrier, convert lost shield to heal at a reduced potency? This one is actually somewhat fun to use though, so perhaps not.
