I've had issues with timing as well in pug content. The rigidity of the rotation can be problematic in deciding how to proceed. Right now damage feels low enough that holding onto your bigger damage phases is impossible but sometimes it puts you in the downtime phase where damage doesn't feel great. You just have to pray to Cthulhu that you end up in the right place for dps checks. I used to be able to manipulate my damage better to fit phases, so personally I don't like lack of flexibility. Now, maybe an increase in damage would make it feel less like your head is under water and you can't get above for air. However, I still see the current layout as problematic. Maybe with some tweaking, it'd work more fluently. 4.0 was a nightmare and they really fixed it and we ended up with a good rotation. 5.0 isn't as bad as 4.0, but it doesn't feel good to play to me and that's all I care about. I could care less about lore or egi interactions. Pets will always be glitchy, always. So more egi interaction will always mean more glitch.

I'm with Gallus. Compared to some of the other jobs it feels like we got left by the wayside a bit. Dots falling down, man it hurts. Having to move from r3 cast or getting interrupted hurts. And heavy movement content can take some time to deal with. Bahamut feels clunky. If the numbers are buffed a bit, it will be something that we can live with. However, casual players are definitely screwed playing this class, the skill ceiling is high. As far as I'm concerned a class that can't both work fluently for casuals and reward professionals for their endeavors has fallen short. My FC is casual and everyone who have touched summoner, said nope. I can't do this. There is too much going on. I will also say group ups with smns in casual content has not been going well, they tend to struggle hard overall. I'm trying to be vocal because I want to see changes that will make it easier on everyone.
I will continue to try to maximize my rotation and keep moving on, regardless of how it plays out since this is my beloved class but I am waiting to see what buffs we will get, if any.
