I think we can agree that:
1. Movement and postitioning of your toon is kind of important for any class, vital for mdps to be effective.
2. Supply drops are not predictable, are instant and are bound to a faction.
Problem:
No matter if you push, withdraw or skirmish the risk to run into a box exists as soon someone goes down.
In the heat of battle they are often hard to recognize.
On the maps are bottlenecks and passages that can be blocked by supplycrates very easy.
(E.g: Happened last week in SL at the passage Destro WC - South Keep.)
Since they are bound to faction they cant be cleared sometimes.
Possible Solutions:
Remove the collision (of supply boxes) entirely.
Alter the collision to pyramid or spherical shape so one can just simply step over it even with a slighly longer path.
Paint it golden yellow and/or blazing orange
