I just analysed stats a bit, i am probably completely wrong on some points
Terran
Attack:
DE ==> Mass de can overcome cat/etd emping, but is a bad choice
DE ==> Terran with low syren
CR/BS ==> Using Syren as flak, Terran BS can attack Xan
BS ==> A big BS fleet can overcome ETD emping
Defense:
Weakness:
FI:
Pegasus Take care of Xan Fi fleets, unless they are prepared to throw in some co as canon meet
CO:
Pegasus shoots nicely on Co
FR:
Cat Fr cld come for you With A teamup to scare of your wyvern
FR/DE :
Xan fr + DE will most probably see you as their best target
DE:
With both Chimera and Buccaneer shooting before Wyvern Terran is hittable by DE
==> having enough Syrens provides an answer or way to scare attackers off
CR:
Etd that are preparred to take some losses from your small de fleet including zik might see u as a target for their CR. With the ranger stunning your dragon they might be right
Cat cr could come for you (they'll need to emp you tough as they always do)
Cathaar
Attack:
FR: ==> Cat with low amount of Roach
==> Decent amount of bw makes it possible to attack smaller xan
==> Terran before BS comes out
==> With zik co being their roiding fleet – cutters prolly would get trough on you
==> etd is a good target if you have enough fr to overcome it's Vendor
CR ( Cruisers are very cheap and this is noticed by the dmg they do etc.)
==> A big enough CR fleet can take on terrans
==> Xans with low amount of spectre might be worth the losses for their roids
==> With buccaneers shooting before your tulas, zik might not be your best choice
==> Etd Ranger and tycoon will target your cr before your tulas get a chance to do anything.
Altho with only 60% efficiency, i think ETD cr are stronger then cat cr
Defense:
Weakness:
EVERYTHING (except maybe cr/bs with that tula)
Xandathrii
Attack:
FI: ==> mass fi fleets can hit ziks/etd with low amounts of co
==> mass fi fleets may overcome cat emping
FR ==> cat, etd
FR/DE ==> with spectre killing off wyvern, it is possible to take out terran targets
Weakness:
BS:
==> spectre shoot syren before they shoot wyvern, some terrans might find the losses worth your roids
CR: ==> Build enough spectre/shadow to kill of emping CR
FR: ==> CAT Fr might like you
CO: ==> big zik/etd co(with fi support maybe) can take out you precious fi
Zikonian
Attack:
CO:
==> A nice and decent sized co fleet can get through the cathaar bw's
==> If u are preparred to take some losses, attacking a xan might not be a bad idea
DE: ==> Your buccs will pwn Terran Wyvern
==> emping your de might proove difficult for cathaar
==> If you steal pegasus, bam suddenly xan becomes a target!
==> ETD if u get past the vendor
==> various combos possible as soon as you steal ships
xan/etd co won't hurt your co fleet when hitting xans
Weakness:
fi: ==> big fi whoring xans will eat your co alive
Fr: ==> cats with enough BW
FR/DE ==> xans with huge fr/de fleets might love you
etd
Attack:
Co:
==> A nice and decent sized co fleet can get through the cathaar bw's
==> If u are preparred to take some losses, attacking a xan might not be a bad idea
CR: (ETD Cr are stronger then Cathaar CR)
==> With a decent built CR fleet you should be possible to take Terrans and stn their dragons
==> xans with low spectre/shadow
==> ziks with low buccaneer
Weakness:
Fi:
==> large xan fi fleets might be a threat
CO: ==> Altough a decent amount of dealer should protect your from zik co incs, maybe some might attack u
FR: ==> Xan fr will eat ya alive
De: ==> IF de fleets get trough your vendor emp they will probably hurt you (certainly buc/drake)
CR: ==> with 3 classes shooting on cr in t1 or t2 u should be fine
BS ==> a big bs fleet might overtake your emping
