Good time of day to everyone!
A simple thought experiment with potential large consequences. What if Scroll usage followed spellcasting rules? Rules in question are: verbal and somatic components. To cast a spell using a scroll you have to hold it up (somatic) and read the spell on it (verbal). What are your thoughts on it? Mine are down below, just skip if you don't want to read 'em.
The dev team, as some of their members mentioned in the past, tries to follow the design philosophy of meaningful choices: benefits incur restrictions, which in return foster creativity in mechanical expression. Right now the scrolls are direct and almost unrestricted access to spellcasting classes' most powerful feature - their spellbooks. You can get clubbed by an ogre, and a sheet of paper thrown at it will blind it save-free, along with savelessly unsummoning most things.
Would this render scrolls useless? No. Would it make Silence incredibly overpowered? No, you can still use potions and wands to run out, use a mords to dispel it. Having to perform the verbal component and being vulnerable to silence would give a meaningful weakness to a by far one of the most foolproof features. You also still have to cast Silence on yourself OR your summon to make it work, thus cutting your own access to scrolls along with trying to impose this restriction onto your opponent. Casting it on the enemy is: a) a double edged sword, as they can use it to silence you; b) imposes a save, which will be easily passed.
To be honest, the scroll usage looks somewhat oppressive, and doesn't adhere to one of the key principles under which the other features are designed to be. It will in no way disable the use of scrolls, but will add another element into consideration, along with a chance to lose concentration when getting smacked in the face.
If it is at all technically possible, that would be one restriction that shook up the existing meta and gave a new tool for avid PVPers. Also cloistered clerics would suddenly become cool, so there's that.
