So I've been using the Nozzlenose H-3 with varying success and I have a few questions for professionals about it. Fist off, is it considered long-range or mid-range because it has a high range for the kind of gun it is. Also, for ranked mode, should I use the Suction Bombs or the Point Sensors? I have been using the bombs but I want know which would be better. Thanks in advanced.
Personally I'd classify it as close-mid range if you're going to engage in battles. The amount of travel time the shots take from it's furthest sweet spot is simply too long.
I mentioned close range because if you manage to swim up to a squid unawares, firing off your salvo into that squid is a guaranteed kill and has the least possibility of any of the 3 pellets missing. At least in my experience, rapidly swimming up to a surprised enemy and unloading 3 pellets into him is sometimes way more effective than playing the 'fire and miss' game whereby you get jumped by a second enemy squid or simply get out-maneuvered by said enemy.
At long range (well, close range too actually), any squid worth his salt will be moving about so fast when he spots you that you might end up hitting him with 1 pellet per shot. I don't think I have to explain why that's a bad thing...
H-3 is good at supporting teams thanks to suction bombs (wonderful on Tower Control) and Echolocator shouldn't have to be explained...although cold-blooded is a major PITA. H-3D on the other hand is more of a 'hunter-type' variant where you'll be actively gunning down lone squids. The weapon simply isn't designed to allow you to handle more than 1 squid at a time properly.
As a comparison, if you want an actually good mid-long range weapon with the objective of splatting, either of the Bamboozlers outshine the H-3 completely in this area.
As a little tip, get at least one throw range up for suction bombs if you're playing on Moray Towers, otherwise you have no way of harassing E-Liters at all.
P.S. I wouldn't call myself a professional H-3 user, but I did spend a great deal of time messing with it in Turf Wars (particularly the H-3 variant) and these are my general thoughts on it.
