If you don't think the "N" is competitive in the MA, you're doing it wrong...
any plane can be competitive in the MA, given proper use..
the issue is the 5ENY value.. even with WEP the N has no "super power" like most other 5 eny rides.. climb rate is average, acceleration is average/slow turning is nothing too great, e-retention is slightly better than average but not great, firepower is above average but not in 4 hizooka or 30mm territory.. it has amazing stability in a dive but so do other planes with a higher ENY value. roll rate is good but not the best either.
and after it runs out of wep, its equal or inferior to the 20 ENY D40 in performance.
its only "wow" its its the most fuel efficiant.. jug.. which is more or less a moot point in the MA anyway.
