If we both agree that the M1A2 SEP is better than the Leclerc and 2A6, and that the difference in capabilities between the Leclerc and the SEP is significant, I can’t see why there can’t be a 0.3 BR difference.
If anything, the SEP (and other similarly-capable MBTs) should go up in BR, not the Leclerc going down in BR.
Radar signature still exists, especially for powerful radars like with the BUK. You can kill them pretty easily if they are not chaffing / multi-pathing.
LDIRCM affects only IR missile SPAAs, like the IRIST, so stuff like the Pantsir, ITO, ADATS etc… can still be a threat.
Pantsirs can often catch you out before you even shoot off a couple IR missiles, especially at ~6km and closer. You can of course shoot them off further away, but that just gives them more time to intercept them too. You kinda have to balance your range to make it practical. 6-9km are the distances away I usually stay at. Maybe closer (3/4km) if the map is mountainous and I can abuse spawn-camping SPAAs’ lack of LOS on my position.
Laser-guided JAGMs, for example, can just be fired off without direct LOS, so you can fool them into shooting those instead of focusing on your helicopter, effectively depleting them of their ordnance without having to expose yourself at all. If they notice that you’re just shooting laser-guided ATGMs, you can still kill them if they remain in an exposed position.
Some SPAA players are smart enough to get behind cover, and peak the other side of a building once you fire off your IR missiles at them. The IR missiles would lose track and then miss, so they would still be able to engage if necessary.
With laser-guided missiles, you can simply switch to the correct position before they impact.

Agreed.
Definitely too strong before. Now I think quite a lot of them are too useless. 😅
Can’t rely on Gaijin to fix the BRs of anything properly…
Yeah, maybe they’re similar in general performance.
In urban maps, I think Leclercs will generally do better; however, in hilly maps I think the 2A6NL will generally do better. It really depends on the situation.
That being said, I think a French SEP would do much better than the Leclercs.
