In response to this remark, I feel obliged to point out that the Cmdr principally responsible for calling attention to perma-boost is Alexander the Grape
messing about with the flight model should not be based on PvP
On the topic of perma-boost, though, I'm not sure that it is really messing around with the flight model - more just considering the consequence of ED 3.0 +50/+50/+50 charge enhanced distributors, which (even more than in 2.1) are overwhelming a large part of the game's prior decision-taking, just as for example 3000 Mj shields on a fast medium long since overwhelmed the prior skill of keeping one's shield up during SCB use. In both cases the error margins are now so generous that much of the prior skill discipline ceases to exist - the desired outcome is near-guaranteed, with good pip management or merely middling.
I agree with you entirely about the PvP/PvE thing but as ever we come back to the other side of that coin: unless and until PvE-ers are regularly faced by NPC opponents max-specced as a PvP combat ship might be and employing apex tactics accordingly, exclusively PvE players are being exposed to a fraction only of the game's combat development, leading to artificial forum debates. Perma-boost should be something that affects the character of both sides of at least some PvE encounters ... not just one side.
I hope that Frontier will build upon their new wing missions so as to introduce a whole suite of optional PvE combat challenges that mean that balance discussions can take place with everyone having a greater degree of shared perspective and interest in the outcomes.
