Alright, ended up resetting, find myself farming drakes because the flat bonuses are way better than the % ones on items, with the level cap and 600m mana shards, seems a bit.... backwards. I wouldn't say the level cap solved the problem because now my heroes still do 85k damage, FAR FAR bigger than even lich health :P
Flat bonuses are great for reset heroes when you have very few shards, then when you have a good amount the % are better, but at 600m+, the flat bonuses become useful again. Although, truthfully at 600m shards, you're way ahead of what content I have in so far!
Before the last patch my goldmine was making well over $100m/s, now 3.4m/s, it was either a nerf to shard productivity or a bug. For now, I don't bother resetting, because there'd be no way to get the buildings back up to current level even with the bonus shards I'd get.
A good "trick" with liches I've found, reload the game so all heroes are at the entrance to the forest, more than half of the liches die before they can get in reach and the others can be outhealed.
@gamelton I've been running 2 high priestesses, 2 longbowmen, and a mage since below lvl 1000 on liches (not upgraded at that time) occasionally someone died but they'd back before anyone else died. Now at lvl 1.1k they're doing it fine at 1/6.
In 1753 was "definitively identified" but it was used from a few centuries before. I had a lot problems with all years, it is not clear the concept "discover".
Got stuck just after clearing the level with the lift, turned to heavy just as entered lift and it spazzed out, now i'm on the "going to next level" screen but no tio....
 "SAGA Idle"){kind=icon}
 "Idle Evolution"){kind=icon}
 "TIO"){kind=icon}
 "Psychout"){kind=icon}
Super high levels will still make heroes overpowered, but I'm okay with that(although the stats on item level might need a slight curve)
