The better pilot will win.. Even if less engineered
I am not for changing engineering, much as I considered the size of the gap it created to be a mistake. But........................
How much of a skill gap does it take to overcome a 50-75%, or even higher, gap in weapons power and shield/hull strength with 15-25% more speed and maneuverability in the same sized package between G5 and unengineered? It's not trivial that is for sure. Now, if we want to compare the relatively easy to reach G4 level of engineering vs the PITA level of grind that G5 can be, yea, it's not that huge a difference. But unengineered vs a G5 meta PvP build? That would take quite a bit of skill to overcome in a duel.
That said, engineering is here, it's settled. Taking back from players is far more problematic than never giving them something in the first place. And, people wanting a vanilla ship PvP experience could create a PG aimed at that. Otherwise, in addition to increasing their skills, they need to get engineered to at least G4 if they really want to be competitive. Please, no one tell me about this one person they know that can take on a wing of elite G5 FDLS gankers with a single unengineered iCourier. They may exist, but they are the exception.
