@SHMITTY8900 I would say damage is far more important, since you'll be farming a lot of the gold, I get about 200k gold a minute now, and ive just gotten my health from 1000, to 8000 in under a day.
I think the item design has become a popular idea with this game (and one I would like to see) it would give the gems some use rather than upgrading a lvl by 1, and maybe with an added defence feature, you could buy new pets, weapons, and armor, that increase a range of stats (but keeping attack speed at max 0.15 per second), I also personally feel a prestige mode wouldn't really be needed if the later game was more interesting, and progression was faster.
Not sure if it's been sais already, but it would be nice for the warrior to gain exp with each monster kill, this can increases his stats slightly, then when a high enough level is achieved, and an upgrade route. Barbarian (increased attack) advanced warrior (even stats all increased) and a knight (increased defence) but I also think for that to work, there would have to be balance changes, and more updates.
now i'm making around 100k gold a minute, it would be nice to not have to click an upgrade 300 times to spend all my gold collected over night. maybe an invest all button, or a times x amout with each click.
this game must love the number 9 haha, the max display of warrior attack is 999, but the damage continues beyond that. I still feel like I should be doing more damage for all I've invested into warrior and rogue damage.
