"Using" the matrix isn't just for hackers and riggers, though.
Being able to coordinate actions via commlink signal across distance or outside of LOS is a huge advantage.
Tagging enemies in AR for the sniper (or the clueless, who failed perception checks) is also highly advantageous.
Basically, having a working matrix connection is what allows characters to be "in the know" based on what amounts IRL to table-talk.
If the shadowrunners are jammed out of their commlinks, things become much more complicated!
And this is an avenue, that many character AND players will acknowledge is important... FTOC... They just don't want to
deal with it (as so much play the matrix support character who would normally co-ordinate all these actions and activities) but they want to use them.
Now,
basic matrix actions - like more background actions they are more then willing to do. ("like, just 'Horizon' it dude. Geez!") because this doesn't require an investment in skills so much as tech for simple things. But hack a door? or jam a commlink? Dive a host? Nope, not interested.
This is generally why I make an NPC available for teams to fall back on and "use" for their matrix acts, so
they can play as they want.
-And gives me plenty of "plot armor" to make things move in directions I think the group wants, that an actual player wouldn't allow.
Team doing well on their stealth run, but seem itching for something to shoot? The Decker flubbs up and trips an alarm..
Team hurting badly through poor rolls and not poor planning? Decker finds a way to seal a door to let the team limp away..
The trick is to not allow the "NPC" to outshine the players... and I have developed a system that works for me, while making the NPC both memorable and effective in his role, not flashy enough to "steal a scene" (in fact, unless directly needed, the NPC should be almost invisible 99% of the time.)
