I'll be brief. The extra click damage from the reset achievements is pretty underwhelming and only relevant the first fraction of a minute after a reset, especially since it can't be multiplied by Bush Whacker's upgrades. I would recommend one of the following changes to make it better:

1) Apply the click damage buff directly to Bush Whacker as a flat damage increase. This will make BW matter more as the game progresses.
2) Change the achievements to give 50/250/1k/etc. starting gold on reset, so we can immediately take idle crusaders and skip the somewhat annoying early stages.

I'd personally prefer #2, but see merit in #1. Feel free to discuss this.
