It's not as good as you think?
The only reason for perking it as far as I can see is that it's real popular.
Short legs, short clip, average leathality, turns OK but not excellent, pretty fast, cockpit viz average.
Where's the threat? Pretty fast?
How about we perk everything that's "pretty fast"?
As many have pointed out in the uncountable "perk this, perk that" threads that have graced this board, perking something will only make the horde change to the next aircraft with a perceived advantage. That's what happened when they perked the -1C.
There's NEVER going to be an even distribution of players amongst aircraft types. There will ALWAYS be a few aircraft that are the most common in the MA.
Do you see many Spit 1's? P-40's? A6M2's?
There's NEVER going to be an average distribution. It's the way it is and always will be UNLESS HT decides he wants to change something, to introduce a mechanism that forces people into particular aircraft. An RPS would do that, for example.
