I just completed getting all of the doggo's finally and got my ultimate doggo, and so far I have to say these Primal were some of the easier Ex Primals compared to Heavensward. Shinryu did provide a bit of a challenge when it first came out, but after that, each new one just started to drop down on difficulty.
I will say though that while farming them, the longer than 30 sec gimmicks, like Byakko's skydiving part, or Suzaku's Dance Dance Revolution part started to get a bit annoying after having to do them for so long, even though they are fun to do (Just for context, I had to get the 99 totems for Byakko, so imagine trying to farm the doggo and having to do that sequence that many times @_@). I never got tired of blocking the big huge sword from Susano though, I did like that part alot!
I was expecting a bit of a harder fight with Seiryu, being the last Lord and all, but it wasn't as hard as I thought it would be. He is still 100x better to do than Zurvan though. I never wanna see anything like patch release Zurvan ever again. Also have to say that Suzaku, while a pretty easy fight, was extremely annoying for some reason. While the fight was fine and I liked the music, the stupid color panel mechanic was horrible (especially with those who have low latency), and the area is NOT nice to RDMs, since one misstep with muscle memory on Displacement or even Corps-a-Corps if the boss moved can spell disaster.
But yea, these seemed like very easy Ex Primals this go around, and I have to say some of the music for them is absolutely fantastic. Tsukuyomi's theme is still one of my favorite tracks in a Ex Primal, and the fight itself is very fun, even if it has its long drawn out add phase, but I never really minded too much, just cause everything from the music to the visuals was just awesome. Of all the doggo's I though I would have to farm, I had no problem if I had to go through that 99 times, lol.
I do need to say though, that when these Ex Primals get their "Increased drop rate" for their mount, I feel SE needs to up that just a bit...especially if they plan to have more grandiose Phase changes in the future. I know my luck is bad, but there were some times I would go 30-50 totems and never ever see a mount drop doing consistent runs. Lakshmi, probably one of the faster and older Ex Primals, required me to do the 99 totems to earn the mount, just cause I rarely saw any of them, which seemed off when I would check my inventory and see I was on the 25th totem that day, and saw more Bliss Shrouds than mounts (Heck, to this day I have never seen the Aquarium item drop ><. Yea I know its not part of the Increase Drop Rate, but still).
So yea SE, lets jump that "Increased Drop Rate" up just a lllllllittle bit more.
