I got a love/hate relationship with AE2. If it wasn't for the storage, I would get rid of it ASAP. I was a very big fan of AE1 and I used it in every single 1.6.4 world I have ever done. (incoming rant)
My problem is that my first step in any world (after basic pulverizer) is to set up a ME storage system since I just cannot stand dozens of disorganized chests which you have to waste so much time going through, fixing up, and all that jazz. Neat storage is always my first goal since it makes automation and doing mods in the future a ton easier and more organized. AE2 takes way too much time to setup initally... I mean I literally stand next to a puddle for 2+ friggin hours and watch Youtube videos. After that, I gotta do some bogus like charge up some quartz using some incredibly slow and rage-inducing machines. I don't care enough to automate anything in the mod because you need to go through the slow parts to do that and I do not need to get that far into the mod.
I know opinions and all that, some people like the new AE2. Well, to me I have to re-learn the
entire mod just to
accomplish what I was already doing before. That is just aggravating to me. Nowadays, I utilize every way that can take me around using AE2 as much as possible. (Also, f*** meteors. I learned too far into my game that I could turn them off and I have at least 6 craters within 500 blocks of my base)
I gotta say though, if it weren't for the mod irritating me so much, I never would have utilized so many of the other mods in my mod pack. So in that regard I actually thank AE2 for pissing me off
