This is a decently kitchensink modpack with a few changes fitted around my play style. The pack can be deadly but, if you can avoid this, progression should be pretty quick. However there are a lot of things to do late game.

Most notable changes

4k, 16k and 64k ae2 cells are cheaper (I hate the recursive recipes).
Ores generate in rarer bigger chunks, some ores might be hard to find, but you should be able to find workarounds for those.
Pitchblend is only found beneath oceans and mushroom biomes (and of course in the end), it is quite abundant there.
There are more caves and open spaces underground. This makes the world more beautiful (in my opinion) and a bit more dangerous. :)
Most early game energy storage is disabled to incentivize the creation of sustainable ways of producing energy.

Points of interest

Farming rainbow trees can be a very good source of a certain metal.
Finding villages wont be a problem and you should be able to obtain some nice starting items there.
I can recommend automating everything (mining, lubricant, ethanol etc...). If you are familiar with rotarycraft this shouldn't be a problem.
It is advised to use Pam's mob drop crops (instead of more traditional monster farms) when playing on servers.
It is also advised to craft a hammer from the hammerz mod as soon as possible, this will make mining the large ore veins a lot easier.

Potential goals

Nuclear reactors
Chromaticraft
Become a mage
