This is JUST MY OBSERVATION and personal opinion.
The MA is where I do about 90% of my flying today, ONLY because that's where I find my squaddies.
Last night, after a long absence from the CT arena, I dove in their to check out Hblairs set up.
First thing I noticed were the perk points being lower...now say what you want about perk points, but I personally think they are too high in the MA. But, being "cheaper" I expected to see 'Uber-planes High' in the CT yesterday when I logged in. My 2nd sortie (after being shot down by Saw in my quest for a goon that captured a field, grasping a foothold on the French coast) I met no other than two Tempests in my 109. After a short battle I was shot down. So, I grabbed a Dora, which costs nothing. That gave me an almost even playing field with the Tempests. During my 2 hours online I met Spits, P38's, P51's, Tempests over the Channel. To ME, it just seemed more balanced, and realistic, to have this match up with the LW aircraft.
Anyway, to my point.
I honestly think that the adrenline level peaks in the CT. With limited radar (bar dar only when over the channel) you really don't know what the "dot" you vis is, until you start to recognise little 'flashes' that the dot may give out, such as you can recognize a P51 or P38 due to their silver glint. I was totally exhausted after flying 1 hour and getting 8 kills in 3 sorties. Wilbuz, Furzy and I were on RW and CERTAINLY helped the SA, as well as the realism of being in a real ATA battle.
Bottom line, the CT might just be an "Adrenline Overload" for a few...adrenline is like a drug, you get alittle, you go back for more.
If you haven't tried the CT lately, try it now. They've been getting about 10% of the MA population in their lately, so its picking up.
Please don't turn this into a CT FLAME FEST Laz or others that don't care for it, I'm just simply stating my experience with it, and a possibility as to why some will pass on it, it just *may be* alittle too much "rush" for some human life support systems.
