Reading all the "go back to the good old days" posts, makes me think:
Do you really want to go back to a system in which 90% of the players would never get anything and 10% get everything they want?
I do not...
... even though after 3 years I think I am reasonably well-connected and might be one of those who could likely get some toys for myself easily.
Fact is:
The Technerf system works.
It tells you "this fits" or "this doesn't fit".
It also adds some balancing to the game (and keeps exactly that 10 % of players from getting exactly these combinations that would make them badly overpowered)
The criteria and values for the technerf may not be perfect, and some cells might still need adjusting and re-adjusting, but that is a part of making an existing system work by adjusting it.
Going back should not be an alternative.
Some little injustice is bearable.
The old system was definitely not.
