This is a cross-post from another thread that might be of interest to you:
To bring an entire set of gear (boots, chest, helmet, 2h weapon or 1h+oh) from 3.1 to 8.6, you would need
This corresponds to around 1.900 hours played w/o premium and 1266 with premium
Assuming that you power grind (no break!) for 4 hours per day, including weekends, it will take you 322 days
You need 3400 LP to get one full set from 3.1 to 8.6
As you get 20 LP per day, the LP would take 170 days to generate
LP would reduce your grind requirements from 1266 hours to 313 hours.
So, if you do pure grind for 2 hours per day, 5 days per week, it would take you 31 weeks, i.e. 217 days, to get one gear set to 8.6
Is that too easy? Judge for yourself
Currently, there are 45 different weapons in the game. With our enchanting rework, all of them will go to tier 8.6
Maxing out all of them, assuming no LP, will take 39 years of grind if you grind for 4 hours per day
With LP, to max out all of them, you would need 76,500 LP. It would take you more than 10 years to get that amount of LP. On top of that, you would have to Buy Albion Online Gold, each day, during those 10 years on top of that
For armors, as there are 9 different ones (which will become truly different after the rework), it would be "just" 8 years of grind without LP and 2 years with LP, provided that you grind for 4 hours per day, each day, during those 2 years
The above assumes that you use 0 LP for gathering, refining and crafting.
It also assumes that there is enough mobs, ranging from power level 4 to power level 12
