This is silly.
A Federal Corvette intelligently outfitted and skillfully flown is a serious threat. Maybe all the trash Corvette pilots have skewed your view, somewhat?
You're aware the 'Vette outputs less DPS than a Conda? A non rank-locked, 2/3 the price ship that has at least twice the jump range. The 'Vette is supposed to be a combat ship, excelling in that role in exchange for sucking at pretty much everything else. It currently doesn't 'excel', it just does.The Corvette is where it needs to be. I main a Corvette and as Phisto says intelligently outfitted and skillfully flown it is a force to be reckoned with. There are so many outfitting options already available and as the weapon list and module lists grow so do the options. What you are proposing firepower wise would be more im line with a frigate. However a straight line speed increase wouldn't hurt.
The 'Vette is a powerful ship, no doubt; but its current performance is by virtue of its price tag alone, not the niche it was intended to fill; the pinnacle heavy combat ship. It's currently out DPS'd by the Conda, which sports better coverage, convergence and vision, and doubles as arguably the best explorer in the game. Heavily outpaced, and out shielded by the Cutter, which also doubles as the best cargo runner in the game. The 'Vette? Better turn rate, doesn't double as anything.
The 'Vette is a good combat ship, but it should be great. If you don't agree, fine, explain why (as Renraiku has). But don't bother dragging immature assumption about skill into the equation when you have nothing to base them on. By the same logic one can argue you're likely against the buff because you regularly get stomped by 'Vette pilots.
