And how would you ever establish that 2 players have equal skill/ability ?
You can't.
By whether I win, obviously.
The Python has more and bigger guns, it has more modules and hard points. It has more power. It has better shields that last long enough for the 5 second shield cell change not to be the big problem it is for the Viper (if it manages to power them). Flight Assist Off has not been disabled. Gimballed weapons remain. Power turns remain. If A Python pilot cannot find a loadout/tactical combo to use all these advantages to combat the one advantage the Viper has then by definition that Python pilot is not the 'best' pilot in the duel.
The moment FD turns into 'biggest ship wins' is the moment they might as well remove the PvP element.
Besides - this is not a PvP game. The many thousands playing in Open and non-pvp groups want to have the fun of becoming skilled enough to take their dedicated combat Vipers up against bigger ships and that should not be taken away.
I don't fly a Viper much, I fly bigger ships but having to fear and respect them is very much a part of my enjoyment.
I simply don't care about whether ships are 'unbalanced' for PvP. It's largely an unprovable concept given all the variables from pilot age, experience through to whether they are using a HOTAS and IR anyway. In my experience once you start trying to balance everything around one small game element you're doomed.
People don't like their classes changing every two months or their skills and muscle memory over-written. That's one of the many things that went wrong with Elder Scrolls Online.
'Ooh, ooh - Sorcs are over-powered. Nerf them. Nightblade ambush skills aren't fair. Nerf them'. Most people didn't care but on and on and on it went. They didn't play PvP (if only because the engine was so crap it couldn't handle it). All they knew was they had to respec their character repeatedly when they were perfectly happy with things as they were for reasons that had nothing to do with them.
It's impossible to balance everything. The bigger ships like the Python and Anaconda etc in ED have huge advantages and if a pilot cannot leverage those into putting up a good fight against smaller ships then that's down to the pilot. I guarantee you that despite the New Python being only hours old the pilots who are really good, rather than the pilots who imagine they are better than they are, have already figured out how to play to the strengths and against the Viper's many weaknesses and are rolling their eyes at this thread.
