1: Tinkers construct is the worst mod that you can install because you fall into its trap that you do not use other tools
2: You are a casual player because you play a little around with stuff. A hardcore player I would consider who plays at least 200hours with your pack and you have only a resource overflow after 150hours.
note: my example is horrible but it should give you an idea.
3: Expecting something to be easy no forget that. Mods like TE3 & others just make you brain dead because you play basicly factorio in MINE&CRAFT. Factorio is not a bad game but its settings are deadly for mc.
4: I test ic2c in a better balanced pack then you can do it with currently in 1.10.2
The only op things are worldgen itself and lvl up mod which allows you to dupe ores.
And the Only RF mods we have are forestry and ExtraUtils (25-30mods modpack)
And here is the thing getting the 51.2k iron and the copper and tin you need to make a HV solar panel will take you days. Maybe even weeks because the best mining option you have is the IC2 miner. But that is not as fast as you think. Manual mining is still a thing but at least we still have something to do after 4 weeks of playing. Our fastest player got about 50-60% of a HV solar panel together. But they aim for that.
And to be honest what you tell here is basicly asking for: why can't I have the biggest dick after 2-3 hours of playing (again horrible time scale)
IC2Exps over extreme crafting might be questionable and to much but it still rewards you for something that you do not even know anymore.
effort. How much do you care about an MFSU that took you 50seconds to craft? Not at all right? That changes if it took you 2 hours to craft it.
So again: IC2Exp is not made for people who are pure casual players like you are. its for players who invest time which you do not want to give.
