- Bulls do shield runners from rocks a bit, and they are complimentary, because at some point runners become more expensive and bulls are another collector to buy. They can also be efficient if bought early, even if their cost investment is larger. That being said, they definitely still need more testing and tweaking, and there are also more upgrades coming.
- Yeah the issue is how little ore remains on the ground because of aggressive mountain reclaiming, combined with too much force keeping most of the ores in the air, and tons of collectors blazing through whatever is on the ground. Capping speed a little bit is why it would help runners not tunneling through (or making them gather on the way back too). There are certainly a lot of adjustments to still make to keep the engines running smoothly, especially in the chaos of the late game.
- I assumed you didn't like YEET because runners kept standing on one spot, throwing ore into other airborne ore, which made the ore fall to the ground, instead of being carried back and deposited. This is why YEET can be "actively bad" in the late game. Or why else? That's where short CD could help so they YEET and then do a normal collecting/returning. The plan was always to make it scale with distance from the mountain (or to make Enchant Calamitous Force boost YEET), but guzzler's last tier somewhat patched the situation for now. Anyway, the next patch already has bunch of improvements for YEET.
And yeah thanks, I appreciate people's constructive feedback because it helps me with understanding the picture and different perspectives.
