I don't get it... your first post (OP) looks like searching for advice. And later you say you don't need it
so do you need it in the end? If no, just don't read the post...
RJ-Rob, you may have been around for 8 years but you are a noob in my humble oppinion.
The game has changed and you didn't adjust imho. If you didn't notice the arrival of (L) tools and you didn't try to find out why are they there and how UL has changed due to (L) arrival - you are one big noob.
That is ofc if you really played for 8 years. With your levels I assume breaks you write about were about 1 year long for one month playing... Unless you chipped out massively, if so, I do apologise. But still, I don't think your story adds up well....
Why your return sucks?
1. OF-105 - wrong level for it, at your level (L) tools are the tools, 211 (L) should work well, then check out Z series.
2. CND - I wouldn't go there with your skills to start with, wouldn't mine it amped at your level either (if you did, you are addicted) but if you have to go there ffs use proper tools...
3. CND + OF-105 is a good choice, but only after you've maxed it out a long time ago
4. Maybe you mine wrong places? Did you notice the map changed? I think you did... did you do a research on what's where?
5. It seems to me you have no idea about timing of the drops
6. Decay of (L) amps and MU you pay each time you buy it is a pain for you? What's more of the pain - (L) or minus in tt on each run?
7. Enchancers are there to be used, right. But they are NOT obligatory... it's not that your (L) seeker will stop working when you don't put them on...
All to all... you need to be very lucky to get anything decent. I suppose you will in the end, something that will cover the losses at least partly. After 16h a day it's more than likely... and with all the deposits
But what do I know, you have been here for 8 years after all, and I'm a n00b
