All the weapons sound really good. The Eureka Effect is a fantastic idea. If you get in trouble (eg a Ubercharge destroys your stuff) you can teleport away plus you can teleport to get more metal quickly and the Third Degree could be useful. You could double killing when you crit 
Also Degreaser + Flair Gun + Axetinguisher remains one of the most annoying loadouts in the game. Fucking hate Pyros. |
Pyros are not that bad. Just as long as your friend a medic or there water near by. The wrost are the engineers!
