I think you should know about this video and my comments about this topic.
The basic idea of the pack is awesome, making a pack around SkyResources 2 is a whole new idea and I absolutely like it, I was just bored with sifting and sifting and still sifting without a possibility of automation at earlier stage. I also liked how things gone to the 2.4.x versions, recipes were fine, progression was not too easy but doable. However, after the 2.5 versions I saw things coming in and recipes and stuff changing from far the original progession schedule. Also EnderZoo added nothing but annoyance to the game, it has absolute no effect to the gameplay of the modpack, neither of the mobs that adds are useful or fun - at least not in a SkyBlock pack where you almost never fight with mobs face-to-face, instead you spawn and kill them in a mob spawner where you almost never see them.
Tinker's Skyblock was a great addition and I really wanted to play with it - until I realized you disabled almos the whole mod. It was a terrible idea since Tinker's Skyblock exists for really only one thing: to make skyblock starting easier. Ripping out everything but wooden hoppers is... a questionable decision in a SkyBlock modpack.
Providing different ways to do different things is a good thing. I have no problems with Gendustry and Binnie's or NuclearCraft and ExtremeReactors and AdvGens, they both have benefits and drawbacks and ppl have to decide which branch is good for them.
However. you should always consider not every gamer has a decent gaming box, some of us plays on an older workstation or even worse - on a laptop. BetterFPS and FoamFix helps to some point but these mods are not replacing careful picking of a modpack content - both performance-wise and from the gaming experience aspect. You should consider the opinion of the owners of modest computers.
I can understand this pack is under heavy development but I still not see where you want to go with it. With 2.4 versions I was able to see a direction but at this point I cannot. Take a look at Age of Engineering, it has a strong progression line, clear targets what the player can want to reach, rewards and stuffs what makes the player feel it came from somewhere and go somewhere. In this pack I do not feel this same.
