Not only bugged, but extremely cheap-looking and few of them, all of it for unjustifiably high prices
Orks attract the majority of players? No, just no. Kinda makes everything else you wrote seem wrong and from an extremely broken perspective. I've never managed to interrupt one mid attack. It attacks too quick. It is faster than a number of Ork fast attacks. Don't get me wrong Elves, I collected Eldar back in the day and I still have love for them, I don't want you to be gimped, but you should obey the laws of the game. You can't have RPS where Rock beats everything (including other rocks). That's my experience with Eldar strong attacks at the minute, they have a speed resembling that of the old Ork strong attack. Give the Banshees more pistol options, buff her scream. I'm up for this. But fix the strong attack.
Not to mention the Swooping Hawk 'Shrine' still doesn't even have a name. And none of the Dire Avenger 'Shrines' change their color scheme in the slightest. (With one of them being just a blue helmet, so you can match your helmet with your armor color.)
Sounds like an Ork problem to me honestly and not a Banshee problem, if you lack a weapon that can attack at a speed that can interrupt a strong attack while Marines and Eldar can then it sounds like Orks are not obeying the system and need to be fixed so they can do what everyone else can.
Well, then perhaps you might also want to voice your concerns about SM and CSM being able to completely cancel out of getting stunned in the RPS system/it not applying to them at all. (Since they get stunned for less than a second, usually, and even then their JPA's can nope out of a stun no matter what/get free stuns whenever) And Orks get JPA equivalents too, as well as melee weapons from tier 1-5, or whatever the max tier is, I wouldn't know, since Eldar only have tier 2 weapons.
Orks AND space marines, in sum. Anyway, even if Orks themselves include lesser amount of players than Eldar (which I strongly doubt), it doesnt make my statements wrong - this is not my assessment, this is fact, Eldar is the poorest faction in this game in terms of attention and efforts put into their development in absolutely every aspect. This is the first game in wh40k universe where you can play for an Eldar from the third person - huge field of creativity for this fabulous race in terms of battle styles - and this poor "result" as an outcome
They have 3, don't forget that a chainsword is in fact a tier 2 above the knife surprisingly (poor Scorpion you even had the best infantry chainswords in the game on TT )
I've brought up these issues with CSM and SM cancelling out of stuns. The Stormboy cannot nope out of stuns.
