Some of those achievements are dam near impossible as you have to be in a ranked match which means there are people you cant control that will kill you at every chance.

I suggest you just keep trying out different tactics and don't really pay attention to the achievement you want to complete. Ive noticed that most of them just happen without any real effort.
