I believe the best point made here is encounters with an LA7, generally speaking provide the least enjoyment to a large proportion of the playerbase. Rare is it when one has the opportunity to meet a LA7 1 on 1, co-e and have a good fight of it. There are plenty people who fly the LA7 who are capable of providing this, but they are largely in the minority.
Most of the time you're going to get a HO, a runner, a collision. or get picked while already engaged in a good fight.
Now that is not to say that you don't have these problems with other planes, but a pilot with the personality which fits the above categories is likely to employ the LA7 because its strengths provide excellent opportunities to do all the above. It certainly does those things better all round than any of the other 'dweeb' planes in the set. As such, LALA hate is understandable.
Excellent rant Red!
