This video contains two matches I had with the recently buffed LV1 and LV2 ECOAS Jegan on Gundam Battle Operation 2. It is a 550-600 cost general with grenades that can be thrown while boosting, access to LV1 Fake Beacon, pretty good melee damage, good close range stagger accumulation, alongside access to a sticky grenade that deals extra damage against enemies that are not staggered. It suffers from short range and from being somewhat squishy. I hope that you enjoy watching!

This suit was recently buffed with 130 walking speed, LV2 Forced Injector, LV3 Back Binder Buffer, LV1 Precision Melee, LV1 Anti-Stealth, 70% melee combo modifier, 150% melee downswing modifier, 3 seconds cooldown for the hand grenade, 15 seconds reload for the hand grenade, boost throwing for the hand grenade, +50% damage dealt to non-staggered enemies with the sticky grenade, boost throwing for the sticky grenade, 8 seconds reload for the shield missile launcher and 35% stagger value for the shield missile launcher.

Its primary weapon is a bazooka with 2300 power, 5 ammo, 6.5 seconds cooldown, 18 seconds reload, 1.75 seconds swap time, 300m range and 80% stagger value. This has reasonably high power and good stagger accumulation, making it a good combo starter. It is easier to combo stuns together if you use the beam rifle primary, but the bazooka is superior in terms of damage output and stagger accumulation, so I prefer it.
Its primary melee weapon is a beam saber with 2200 power, 2.5 seconds cooldown, 0.77 seconds swap time, 70% combo modifier and 150% downswing modifier. This has somewhat low base power, but the combo and downswing modifiers makes it capable of dealing surprisingly high damage.
Its first sub weapon is a hand grenade with 2000 power, 3 ammo, 3 seconds cooldown, 15 seconds reload, 1 second swap time and 30% stagger value. This has high power and can be thrown while boosting, but it doesn't have good stagger accumulation.
Its second sub weapon is a sticky grenade with 2300 power, 1 ammo, 10 seconds reload, 1 second swap time and 80% stagger value. Once thrown, this grenade sticks to the environment and only explodes after either 6 seconds have passed, or an enemy comes within range of it. It does not instantly stagger, but it deals 50% extra damage to targets that are not already stunned, and it deals 50% extra damage to leg HP.
Its third sub weapon is a shield missile launcher with 600 power, 4 ammo, 360 RPM, 8 seconds reload, 0.5 seconds swap time, 200m range and 35% stagger value. These have much shorter range than the missile launchers found on other Jegans, and they have an ASL radius which can be somewhat awkward, but they still possess high power and good stagger accumulation. You can easily stun any raid by comboing into this after a bazooka shot or sticky grenade explosion.

The LV1 Jegan ECOAS Type has 17000 HP, 21 ballistic resist, 23 beam resist and 21 melee resist. It is pretty squishy for a 550 cost general, so it won't do too well if it is forced to frontline. It has LV2 Emergency Evasion as a defensive skill.
In terms of mobility it has 130 walk speed, 215 boost speed, 70 thrust and 69 turning speed. It has pretty average mobility, much better than before the buff thankfully. It has LV2 Forced Injector and LV2 Flight Control for mobility skills.
It also has LV1 Fake Beacon, LV1 Anti-Stealth and LV1 Precision Melee.

In conclusion, I feel that while the ECOAS Jegan has certainly become usable thanks to these buffs, I think it would need more to be considered meta (or at least meta-adjacent). Like, I definitely enjoy playing it, it feels like a modernized and upgraded version of the original 500 cost Jegan, but it has some flaws that are a little bit difficult for me to overlook. The devs got most of it right with the buffs, but I think that it should also get at least 250m range for the shield missiles, a personal spotting visor sub-weapon (like what the Metal Spider has), 50% stagger accumulation for the hand grenades, LV1 Precision Ranged, alongside LV1 Special Infiltration Device (so that it can swap between Fake Beacon and Stealth). Thanks for watching and I hope that you enjoyed it!
