Well, thats because you're focusing on a single complex form, deciding you'll rarely ever use it, and then saying you'll hardly ever use any complex form because of it. You're also forgetting the whole biodeck, and a few bonuses to matrix stuff. While not the most impressive initially, the echo's can start giving you all sorts of improvements.
Technomancers also make excellent faces, when not picking up augmentations.
But you are right, currently right now, lots of the complex forms are like "super" versions of matrix actions.
Hide/Static Bomb
Hide increases your god score, and only affects a single target.
Static Bomb on the other hand, doesn't increase your god score and hides you from all targets. However both of them.. kinda need a little bit wording help.
Jam Signals/Pulse Storm
Jam signals is another one that increases your GOD score, turns one device into a jammer that screws with everything.Now cause you're a persona, not a device though, it hardly effects you unless you're trying to mess with a device near that one.
Pulse storm however, its more permanent. more precision based.. Though I think something might be badly worded there... since its a duration of I
Grid Hop/Transcendent Grid
Grid hop has potential of increasing your god score. And you're still only one one grid.
Transcendent grid bridges them all together, and lasts for a few minutes at the very least. You basically no long suffer penalty of noise because of your grid. Very handy when there is a lot of traffic on one grid.And there is hardly any reason not to bring it up to level 5 or 6.
Spoof Command/Puppeteer
Spoof increases god score, needs marks, and such. But it can function fairly easily for most everything you'd need it to do.
Puppeteer, the +4 fade does hurt, but since spoof can cover most of the things, really you'd probally use this more as the ace of the sleeve.
Edit File/Editor
Edit File again does most of what you'd need here. Its a bit risky if you've not done it right, but still.
Editor - You need a file changed in a jiffy? Thats what this is for. Getting it done now. With a point of edge, you can get something edited out greatly, in a single turn.
Data Spike/Resonance Spike
Data spike has two resistance checks and increases your God score.
Resonance Spike however, only a single resistance check, and it doesn't increase your god score.
Overall, looking at the abilities and such, I feel the technomancer's complex forms currently are more of the ace up the sleeve. Being one, means you can have those aces. Being a decker means you're not having them. Though it would be nice to have more of them of course, and have a slight decrease in fade cost for most as well.
As a mage, you don't use magic fingers to open doors do you? You don't expect an adepts armor power to protect you better than real armor?
I don't really see the point of making a techno if you're almost never using your complex forms. In my opinion, I'd rather see Fading lowered across the board and more/new complex forms (that do more stuff Deckers simply can't) enter the game to better distinguish them. Deckers are already simply better at the hacking itself and have a higher potential to take a second role; rather then make them identical, I'd rather focus on the stuff that makes Technos unique.
I've got no experience playing Technomancers, but it does seem that they take a lot of stun damage just doing what a Decker would be doing anyway...
also, I love seeing more things that distinguish one archetype from another.
Only if you're constantly using the complex forms to perform the mundane tasks that a decker handles.
I think one of the biggest problems overall that a technomancer faces is that they are seen as supernaturally mundane, In other words, some of the things they can do break the laws of physics and such, like using a Machine sprite to run diagnostics on a handgun to boost the technomancers proficiency with the weapon beyond normal technological limits.
