Everything Zenimax has pushed out thus far has terribly vague descriptions.
Their patch notes are incredibly vague and their in-game descriptions even more vague. There is confusion with many abilities due to their lack of explanation. Crafting materials need a more detailed description stating what tier they are used for.
My biggest issue is with stat buffs on the character sheet. They all look like this:
Mundus Stone: Increases 'X'
Food Buff: Max health & Magika Increased
Molten Weapons: Weapon Damage Increased
Why do you hate numbers Zenimax? Does it go against your so called 'immersion' philosophy? Show us some numbers and accurate statistics! Not this vague crap that 'X' is increased...we want to know how much it is increased by exactly.
Your character sheet in general is pretty poor. You show the bare minimum of stats, giving players who want to know all of their characters statistics no option to do so.
