One feature that needs to be fixed is the ability to cast friendly nanos on enemies.
A good example would be the Adv nano SparrowFlight.... (there are others..)
This is most certanly not the intended use for this nano...
The same goes for all nanos that have any kind of drawback... Like the suggested changed to the crit nanos.... The primary use for those in PvP would be, not to boost crit, but to debuff the enemies inits....
So whats need to be done is to stop all casting of nonhostile nanos (aka those that don't start combat) on enemies in 25% or lower zones.
Sure there will be some drawback with that... aka you can't buff an omni as a Clan... but hey... you shouldn't do that anyway!
