Because it will actually give me an incentive to level. What am i meant to do when I reach EOC? Theres no rush for me. If there was more content to play through I would happily invest more time into levelling and into the game. Why do you think its a terrible idea?
What more incentive than 4000 odd levels ahead of you do you need? In game you're free to level up and down as you wish without the dangling carrot of a dumb medal when content is still being implemented.
When that thread was created, granted things seemed a little slow on the development side. However the cows, as a business, with other irons in the fire have never promised content to match player stam bank accumulation. Which lets face it was the reason behind the original post. 'I'm bored, watch me go round again while we wait and get a 'look how much on max stam I spent' medal for it' see below.
Personally, I'd rather let a stoat chew my left arm off than do all that again.
That's why it's a terrible idea. In my opinion of course.
