From what experience I have with Magic IIs. Unless they are fired in near point blank range behind the aircraft, they get flared just as easily. Likewise I’ve had Aim-9Ls ignore every flare and hit. It can be really wierd at times.
You are right, Aim-9Ls are rarely used at those ranges, but I wouldnt say never. (You have now met someone that has fired and scored a kill past 3km with Aim-9L, though granted that was in Sim, not ARB)
Overall though, being overly generous. 1x Magic II at most equals 2x Aim-9Ls in temrs of game value. When combined with the small-ish CM count and limited ammo count in the canons and the issues with the 530s. Its fairly reasonable to see why they are at that BR.
Heck, someone is gunna have to confirm for me. Maybe @Fluffy_Bucketles. But the Mirage 2Ks are also relatively slow. At least I know I outrun them all day long in things like the Tornado F3, I guess the same is true in quite a few other aircraft.
Overall. They have one notable advantage, which is IRCCM at a lower BR than most (though no lower than the Tornado Gr4 with 2x Aim-9M btw) but between how Gaijin models the Magic II and the fact you only get 2. They are fine. OVerall the M2Ks are a solid airframe, but do have weaknesses that can be exploited
The Wiki pros and cons sum it up quite well:
Pros:
- Has access to excellent Matra R550 Magic II and Matra Super 530D missiles
- Very good acceleration
- Great manoeuvrability
- Powerful pulse-Doppler radar
- DEFA cannons deal heavy damage
Cons:
- Poor energy retention at low speeds
- Low ammo count for the DEFA cannons (only 250 rounds total)
- Carries a maximum of only 4 missiles
- Very limited options for ground attack ordnance
vs the F-16A:
- High thrust-to-weight ratio gives it an incredible acceleration
- Highly manoeuvrable
- Able to carry a drop tank to extend flight time
- Access to 6 x AIM-9L Sidewinder missiles
- Has access to a wide range of air-to-ground loadouts
- Vulcan cannon has excellent rate of fire and damage
Cons:
- Does not have access to SARH missiles, limiting its BVR performance
- Very sensitive to weight changes
- Can compress at very high speeds
- No drogue chute
- Cannon ammo is limited (5.12 seconds of firing time)
