To be fair... look at the trailer for GOIO on steam. Not the one for alliance, the second one.
Do you notice anything...?
In trailer there is basically no coverage of engineer class. It's mostly exploding ships, people shooting, people running around the ship, sometimes people repairing their guns (I don't count is as showing engineer) but there is no coverage of classic main engineer dog running around trying to keep ship alive.
Why is that - you may ask.
Well, it may be that Muse just didn't pay much attention to the creation of trailer, but I think we all believe that those people have some passion for their creation and trailer is a big part of showing off the game, so I'd rather dismiss that theory. Let's say I just don't believe Muse to be so stupid/careless/whatever.
Or they know that being engineer is not exciting, or just not a good part of GOIO experience, and they deliberately didn't show engineer gameplay. Which is quite problematic, since due to the game balance, over 50% of GOIO population is engineers! (You need at least 2 on each ship, 2 gunners is nonsense and some veterans prefer 3 engineers).
Tertium non datur.
So in a way Muse are themselves responsible for influx of players who just want a "Boom bang bang boom" kind of experience. Muse have reason for that, I think being engineer is not very exciting, so in a way it's a logical marketing strategy. That's marketing - showing off the good parts and hiding the bad parts. I mean, you don't see iPhone commercials going "we suck at battery life, yo!"
But this doesn't mean that the fact that gameplay of over 50% GOIO population may be considered to be not exciting, or not good, is not a huge problem for this game. Being engineer is a chore, main engineer rarely gets to shoot anything and mostly doesn't see what's happening around him (because he's busy fixing). I've had countless moments when my crewmember went "Oohh yeeah! Did you just see that?!" and I felt like "No
fucktard dummy, I'm repairing your baloon" (i.e. on a goldfish or mobula, with stuff obstructing vision drastically).
This is a wicked problem indeed, with its basis deep in fundaments of GOIO's design and there is no easy way to fix it, if there is any. But GOIO's success or failure depends mainly on this problem in my opinion.
