I appreciate that bombs no longer explode immediately and kill the player who planted them, but:

* Disarming mines takes so long that it's far more practical to just walk over them and set them off.

* There is no longer any good way to open crates on Chrome. Background: It's always been the case that the space bar both took whatever object/NPC actions were relevant and fired the weapon. Before, the crate opened immediately. Now, the shot from the weapon interrupts the object action. The only way to open crates is to switch to the mouse and reaim. This is VERY annoying—almost unplayable in some situations, and in any case way too slow—and why I classify this as a bug.
