I'll concede the point, true, buuut at the same time, nuyen are not an inexhaustible infinite ressource as well, it can be very well controlled by the GM to a fair extent. It's an illusory, infinite resource because in the point of view of a game, nuyen can be found anywhere and not limited , system wise.
The limited amount of role, that, granted, is also downfall. But they make fair riggers, so it's not all hopeless...just..type-casted.
Sacrificing a point of resonance can also become a good idea, like a mage sometimes ends ups having to sacrifice some essence. And with one pt. of ware, you can easily occupy different roles.
Use all that nuyen you dont need for an high level skillwire system and chipjack, and you can be a decent backup face if your charisma is pretty high. Add some high quality Pheromones, you can roll 18 dices for zero karma investment (for an elven technomancers, for example).
You can even be decker AND technomancer and simply pick and choose what style is best suited to the task everytime. (A bit redundant, i'll agree, but once your technopowers outclass your decking, sell all that overpriced drek, get yourself some cyberlimbs with high attributes and armor and go to town as a secondary samurai. It's a bit of a rule abuse, but 2 bulky cyberhands, and 2 cyberfeet can get you 12 extra armor, and a weapon use roll of 9-10 (agi)+ weapon skills (skillwires come back as a useful tool, or even hardwires for cheaper investment). AND fit into a single point of essence if you're using alphaware and biocompatibility. Regular cyber too if you simply dont take skillwires.
