Shuriken particles - not colliding???

Soooo… is it really like that, that the particles only collide with predefined meshes that you have to add manually all along?
If so, that’s really, really terrible!
I made so useful and interesting particle systems with the old engine thanks to the collision function!

Oh and another thing: it seems that the particles are not random but get generated always the same.
Is there an option to change this?
I don’t want an explosion to be always the same!

Mh this forum was so active and friendly some time ago… what happened?

So nobody can confirm this fact that the new particle system does not collide like other stuff?
