Let's discuss the distribution of (non-active) movementspeed on AD items.
Let's take about base movementspeed on AD items (excluded active abilities).
So, which items are there?
Notice a pattern?
- All items grant attackspeed
- 4 out of 5 items grant criticial hitchance.
The itemization is HUGELyYonsesided. It favors ADCs and hurts tanks.
While is mainly an off tank item (uhm, maybe not 
) it is really expensive and offers stats which a lot of tanks or bruisers don't want: mana / ap / crit ( even attackspeed 
)
In my eyes there should be a better access to movementspeed for bruisers and ESPECIALLY tanks - which DOES NOT come from an active item (
), but is permanent mobility.
