Hey GanonBoar, if you like the high power action of the .52, perhaps you should give the .96 a try. It's always a 2 hit KO which is nice compared to the .52 which can waver between 2 and 3. The normal set is nice as a support weapon where you can pick off opponents from afar while building up echoes for you team with the sprinkler. On the other hand, the decorated variant is nice for pushing the other team back by keeping them at bay with the wall and getting behind enemy lines with the Kraken. The superior range compared to the .52 really does make up for its slow rate of fire.
Or if you want to get away from shooters altogether, how about the Custom Blaster. It's a short range weapon ideal for sneak attacks. Throwing random point sensors can help sniff out hiding enemies and it comes with a Bubbler which is always nice for getting out of a bad situation or pushing forward. I do recommend the jump and shoot technique; it prevents shooting the ground which reduces the effectiveness of the blast. Also the blast is a 2 hit kill while tje direct hit is an OHKO which is very nice.
Hope this helps you find something new. There's a lot of weapons I like, so I'd really recommend them all, but that's not feasible.
