I certainly don't mind helping out, seeing how we don't have that much of a timezone difference (unless your profile lies about your local time, which is GMT+0 as far as I can tell, I'm on GMT+2), let me know what time is convenient for you and I'll make a plan (sometime in the evening of course, or early morning).
I suppose I could try summarize a few points about each of the runs.
Berz (giant bee)
Equipment: 2 x Shotgun/Blaster type weapons, Shotgun/Custom Shotgun preferable.
WB: Burst Fire Bit on your support bot (increase attack speed for you and your teammates, speeds up the fight by a lot); WB doesn't matter much for non-supports, but Blaster bit if you really want to maximize your dps.
Bot Types: Anything goes assuming they aren't slow as hell as you will need to chase after Berz for 2*/3* (maybe even 1*, not sure).
General Strat: Find a good spot, settle down and burst his ass down, WB whenever possible, give Burst Fire to teammates whenever possible, learn his dive/AoE/bomb animations so you can anticipate and avoid them in time. He will travel from/to different locations on the map during 2* and 3* after a set amount of time, you need to learn these locations and learn the correct route to take to reach him. This is absolutely vital for 2* and 3* as you want to minimize the downtime from chasing after him, as he will try regen his life once he has reached his new location and left unharassed.
1*: Can be soloed and dualed with reasonable ease, I think.
2*: Easy with three skilled players. Probably slight of a challenge for two players. Might not be soloable.
3*: Pretty fucking difficult, you'd want a full party of skilled players and plenty of burst firing, and pray that he doesn't troll you.
Frac (ball of ice)
Equipment: 2xShotgun/Blaster type weapons for Air, 2xBlaster type weapons for Support.
WB: Propeller Bits for Air (essential), Burst Fire bit for Support
Bot Types: Air and Support, NO EXCEPTION. Support is pretty hard to do Frac with also, as it takes a lot of time to climb back up the platform if you do get knocked down from there, but Burst Fire bit can make a big difference for the rest of your team.
General Strat: Fight through waves of trash first, then climb the platforms to deal with the boss himself. He will continuously fire small beam bolts at you, they can easily be jumped over/dodged if you keep your eyes open, if you are propellered and circle strafing Frac, they generally will not hit you (though you will need to keep your eyes out for random stray shots aimed at other people and try not fly into them). This gets a lot more tricky when Frac is on low health as there will be many other sources of death to worry about. Regardless, you don't want to be hit by them as they hurt like hell and will likely break something. periodically, he fires a big green beam and rotate slowly, move the hell along to avoid it. After he is dropped to about 50% and 20% (I think, can't remember the exact numbers, hell, not even sure if he does it at all for 1*), he shields himself, breaks some of his platforms and create a few sentries/pillars/towers/objects/whatever you want to call them around the map (look at your minimap for their locations, they have a different icon to the trash mobs), destroy them to deactivate his shield. When you are busy with that whilst he's on 20%, he will fire off a nuke before he unshields himself, get up the platforms to avoid being hit by it. At low HP, he will fire slow homing orbs at you that will apply slow status on you when hit, try avoid them of course. He will also make some platforms detonate periodically, you will see small sparks lighting up around some of the platforms, once all the sparks of a platform light up, it does a blast attack that WILL kill you if you are on it, so fly off them before they do.
So, try avoid his shit whilst dealing damage to him. Air can propeller up and circle strafe him whilst shotgunning his ass (try adjust your distancing to get the most damaging distance for your shotgun), blaster users can stand at the platforms and fire at him from a distance, shotgunners can do the same thing on some specific platforms as well if I recall correctly.
1*: Should be soloable, but with some difficulty.
2*: recommend 4 skilled players at the very least, 3 players with Frac might be possible, but probably is one hell of a challenge.
3*: Bring 5 skilled players, don't fuck around. This thing is batshit crazy.
Haku (Nine-taled Fox)
Equipment: 1x Shotgun type weapon + 1x 3way Dagger/Comination Dagger(gara weapon). NOT EXCEPTION. (Eso would probably argue that, but yeah sure, once you are pro enough against Haku you can go with other options, don't worry about anything else yet) Also bring some other forms of direct melee interegrated weapon. eg. Ace Braver AM, Red Squealer AM, Shino AM2.
WB: Dual 3way Dagger Bit for Land, Slayer Bit for Air.
Bot Types: Preferably Land, Air works too (especially with Trap phase) but Land is a lot more mauverable in most cases and able to equip dual 3way, and dual 3way bit makes a HUUGE difference.
Oh and be sure that you have Packet activated, as happy as possible and with her Trap Sight ability selected.
