Does Enkidu have any use for you guys as the main still?
I haven't used Enkidu in something like 2-4 months. On the other hand, I use Unicorn as my main on every single torment boss, some magicite bosses, and almost all CM content too. My reasonings:
For one thing, you can use Unicorn pre-emptively. For Enkidu, you have to hold a units action and wait until the big status is used before using it (or even worse, wait until the status lands, then wait for a unit to have a free turn to use Enkidu, possibly leaving someone debilitated for 2-5 seconds).
Another mark against Enkidu is that it doesn't work on everything. Boss uses AoE slow? Enkidu does nothing, but Astra would still block that.
There's also the secondary effects. Enkidu does an aoe medica on summon, which is helpful a lot of the times, but you're using it for the cure, and the medica may be wasted. Unicorn applies aoe heavy regen, which heals for more than Enkidu (over time, averaged) and because it's spread out it's less likely to be wasted on overheal (on hard fights at least).
Then there's the "assistance" effects when they pop in randomly after a summon. Enkidu will do a shitty 3k nuke, or a stat break (everything relevant is near immune). Unicorn will pop in and ST esuna someone if they're debuffed, or he will pop in and ST heal your lowest health unit, which has saved my ass so many times in many hard fights.
Not to say Enkidu is worthless, but in my personal experience, I haven't used him in forever but Unicorn is by far my most used primary on almost everything.
In other news, I just did the D280 FF8 CM..... I consider my FF8 synergy to be extremely high, especially after my amazing pull this week, but Ultima (Omega?) Weapon took me something like 20 resets until he used that stupid OTK on the proper units in the proper order.... what a pain in the ass.
