This is week 4 of patch 4.4. Should be safe to discuss.
The simon says mechanic has so much flaws that make the whole fight frustrating and not enjoyable. I really don't want to see this mechanic ever again. On paper this mechanic is easily doable by itself. At beginning, I thought I just need to run around to avoid explosion, which seems simple once you get the [4th] color trick, but the game has too much latency problems to make it so your perfect execution doesn't count.
Especially, casters with latency problems are probably flipping tables during it. At least that was what I felt like. For 12341234 pattern as an example, I've seem people alternating between 2 colors to completely ignore simon says. Unfortunately, that method is 1000% gonna get myself killed. It won't ever work, so doing anything but moving is very risky. The only doable way for me is to chase the explosion by start running in circle at [4th] color twice to completely be safe. It is an uncontrollable factor.
The true nightmare comes after the first set of simon says. I personally am not a fan of falling off platform and yet this time there is an additional hole in the center to force me to move extra careful in a already small environment. Okay, don't go near center. Sounds simple, not. The second set of simon says Suzaku will add either a pull or push aoe. At this point my brain starts to hurt. Just when I'm trying to figure out color pattern and moving to safe spot, here comes a pull. In order to make sure not get hit by the explosion, I must run around the inner circle. 5 out of 10 times, that pull will get me to fall into the hole. If it was a push, it wouldn't be much trouble.
The nightmare continues on third set of simon says. Suzaku pairs close-quarter crescendo with it. Forget about controlling my character to a safe spot, most of the time I fail to not die here because of the mind control. I still could not handle this part at all after 20 tries.
I don't think I can clear this ex fight. No, I don't want to do it anymore. I'm so tired, so mentally exhausted trying to perfectly executed simon says only to get F*** by that unreasonable timed server tick explosion, getting pulled into the hole, or get kill by mind control+explosion.
I farmed all other 4.0 ex primal. Shinryu Ex was exhausting, but it was fun and very doable. Tsukuyomi ex was also very fun with the moon phase change and meteor placement. Suzaku ex on the other hand has been nothing but frustration and fatigue. My friend said simon says is the most BS thing in the game.
