I freaking love the Frontier Justice and Gunslinger, sweeties! X3 Well since the Engie has been my favorite class, and I always go Battle Engie, these new items make it even better to play Battle Engie.
The mini-sentries I love the most since all I ever wanted when I play Battle Engie is to have my level 1 sentry deploy quickly while I shoot down the my enemies. Now with the mini-sentries, I can be more efficient when going the battle field. Also the fact the mini-sentries deploy with full health makes them a great distraction. Now when I see an enemy heading my way, I just deploy the sentry in front of them. They normally start shooting my sentry first, so I start shooting them with my Frontier Justice and let my mini-sentry finish them off.
Oh random question for thought sweeties; has the Engie has always had a prosthesis and covered it up with a glove and then revealed it once he modified with his Grandfather's blueprints, or has he just recently sawed off his arm?
Edit: i forgot to mention how awesome it was to finally being able to move your sentries now. This is great! =D
