If I'm honest, I really like the idea. Now someone in a wing will be have more of a supporting role as well as being able to fight, like a paladin in D&D.
See, that's the thing. On paper, it is not necessarily a bad idea. With a bit of decent world-building and supporting elements, consideration to game balance and playstyles, this can totally work. Yeah, we don't know much about it, so anything could work out just perfectly fine.
Except it hasn't in the past. I've found myself in this situation, "oh this feature doesn't sound so good, let's see how it pans out" only to find out it was exactly as bad as it sounded. For example powerplay-exclusive items. Guess what happened, exactly what the "complainers" said - people would flock to certain powers to collect stockpiles of their shiny loot, then forget about PP again; and certain PP items were more desirable than others, and the PP participation was a mirror of that.
Or let's take missions. I think we are on the verge of the 3rd "big mission improvements" update. Every time when it was said "big improvements to missions" I was so far hopeful, only for it to end in mild disappointment. From the 2.1 mission overhaul I now mostly expect to be worse off than in 2.0, because I first need to grind to super-allied to even see the benefits.

Engineers could turn out totally benign. The healing beam could have such a weak effect barely anyone ever bothers. It could be useful yet balanced with decent drawbacks and reasonable effort to attain. It could be overpowered but behind a grind so massive only the most hardcore will ever have one, and get great results in their overpowered wings assault common folks at CGs.
But all we know now is
a) We need to reach a new, even higher max reputation. And major faction reputation won't count any more (what is it good for anyway in 2.1?).
b) We need to acquire a new currency to pay for engineer upgrades. Yes it is called materials but in the end it is just that, lots of token currencies that you pay to an NPC to buff your engines or shields or guns etc.
c) There will be stat upgrades.
d) There will be more unique modifications.
e) and finally the healing beam, of which we know just enough to be able to say if that is all that is there to it, it is unfitting to the game universe and the balance that has been established.
Sure, knowing all the details why and how we are wrong and why it is going to be awesome, Mike or Sandro or whoever could just chuckle at all us idiots complaining about nothing. Well, part of the complaining is about how we have barely any information to draw from.
It may very well be that picking the healing beam image was just an unfortunate choice, and the actual implementation is the best idea since sliced bread. But we are long past the point where it is enough to tell us "this is going to be awesome". Now we expect to be told
why it is going to be awesome, otherwise we won't believe you.
