I just had this shoved in my face.
The OP is something that's come up often, and it's good when a new game is coming out (especially with new/terms most people haven't heard for whatever reason), but after a while the concept becomes hit or miss.
It really depends on what level your commentating at, and I mean the quality of the tournament. Sure, trying to make everything new user friendly sounds nice, but it actually turns out horrible when you're not commentating a high level event (read: a REAL major, not something that just got codeworded major in the past 2 years or higher). When you're commentating a local event such as a biweekly, there really it eventually gets counterproductive to do this kind of this because in those situations you'd be catering towards a minority of your viewership.
When you look at SC2 for example (which alot of people cite SC2 commentary, which is why I'm going at this point), it's always lost in translation that people are looking at big, mainstream, high level productions. That's pretty much all that gets aired or studied for anything. (At the same time, who's really heard of a local SC2 with the same concept as, say, Big 2?) The SC2 commentaries people look at are a whole string of "NECs" and "Final Rounds" and the likes.
That's not to say that the commentary doesn't need to improve. The FGC as a whole has pretty horrible commentary, myself included. But 90% of us spend most of our time in commentary situations far different that what we're compared to.
And for the sake of credibility, I'm not saying this as a half-cocked random who's only commentated small tourneys in the middle of nowhere (I'm not going to be offended if everybody in here follows this post with a "who the fuck are you?" I've done from as low down as an 8-man house Melty tourney all the way up to being the 1st main commentator in this evo's 2012 circuit. I can safely say there's a huge difference between the two.

tl;dr - I agree with the OP, but i think everybody's throwing a lot of concern without really considering all of the factors of this situation.
