I never played soldier before because I was unable to rocket jump properly. Without mastering it I think soldier was really boring and slow.

After getting the hang of it (i.e. got a rocket jump macro)  I am really enjoying Soldier now. It have mobility, damage and resilience, all in one nice explosive package.

This, and skill-rockets.

One can only ponder what nerfnow stories would be about if I started making it today.
