I'm still on VZW 4.4.4 but have heard about all of the complaints that you speak of here.
I just looked at my notes on that, and found the following. Maybe something of it will help you?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Cross Fingers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Alarm Clock will not over-ride Mute:
Use priority instead:
Open/slide down notification bar on lock screen.
Click on top right icon to open icon page. Click on pencil icon to edit buttons. From available buttons, drag "always interrupt" button to top section; active buttons.
Now when you open the notification bar you can press on the always interrupt button which will then say; priority only and the sound button will say Sound (priority).
Now go to;apps/settings/sound and notification/Interruptions and you can choose the options that you will want to occur when pressing on the Always interrupt button. It states that "Alarms are always considered priority interruptions".
Hope this helps.
It now becomes a one button press.

Battery Life Fix:
I posted yesterday about the sharp dropoff in battery performance after upgrading to Lollipop.
I was toying with the idea of doing a factory reset. Thought that before I did I'd try clearing the cache partition and, just for good luck (from my Blackberry days) doing a hard reset by pulling the battery.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Lock Screen Notifications settings go into settings then sound and notification. Scroll down to while locked & set it to whatever you like
~~~~~~~~~~~~~~~~~~~~~
There is a silent mode its just a pain in the arse to setup. Settings/Sounds and notifications/Interruptions and priority mode. Set interruptions to never disturb and you will get a circle with a - through it icon to notify you its silent. Use priorty mode and you will see a Star icon notification. I use a widget to switch between all sounds/vibrate and priority mode (silent)
~~~~~~~~~~~~~~~~~~~~~~~
WiFi dropout, turn off SmartSwitch networks
under Settings --> Quick Settings --> Wi-Fi you will find a check box option named "Smart network switch", untick it, this should take care of the problem
