I´m still busy with my first map(Been in it for a good 17 hours already tho) and I've found a few things that I dislike. I don't know if others think the same or not, but thought I would share my opinion anyway.
1. Late game lag hasn't improved at all for me, Controlling pretty much 4.5/5 star systems in the map, having all planets with buildings etc(Including 150 mines on each) and I'm running at 6-7 FPS with spikes to 10 FPS, it makes watching battles really crappy...Altho the "Time Dilation" Isn't nearly as bad as in Trinity, so yeey for that.
2. My camera worked fine till like 30 mins ago, On the 5th star system I've found that my camera at 1 point just stops going to the right or down with moving my mouse to the side and have to zoom in/zoom out to get my camera to the right, and this is only on the right side of the star system the rest of the sytem works fine, I don't know what is causing it, but it's just a little annoying
3. Fleet jumps are really idiotic atm, my titan is on the edge of the well as I'd expect, but the rest of my fleet is WAY out of the well to jump making them jump way out of the well to another planet, making them practicly useless for the first minute since they aren't even near the planet on jump in. This only happen as well since this star system.
4. Mines...Mines everywhere...I'd like an easy way to destroy them if they are mine(Having to destroy enemy mines as they are is fine). I had to place my mines on a different place(Due to an enemy being wiped out that was based under the planet and needed the mines on the other side of the planet again) and found out i had to click all of the 80 mines and scuttle them...Why can't we just destroy them all at once, or in groups of 10 at a time?
5. It seems my score board has gone full retard since the last enemy surrendered(He lost 1 of his planets and surrendered immediatly lol)
6. I've found that I love the game, up until the part where I must clean up the enemy, because the enemy has never been able to stop my uprising, since any time he tried to divert my attention to defending one of my own planets, his fleet just got raped by my defenses at that planet. And having to destroy a starbase at every planet takes quite a while to finally get him to surrender or to die because of no planets left.
Will add more as I find more...
Besides those things, I absolutely LOVE the game so far! Loved trinity as well, but this one is even more awesome!
Btw, First map and I got ALL the artifacts 
(And also the Space Ponies achievement 
)
