He can't increasing productivity because he himself is the bottleneck. He draws the art, and the art is the bottleneck. He tried once getting another artist but he didn't like the quality so he decided to do it himself. Thus it will always be this slow. Get over it, or leave. Simple as that. Moaning about it will do no one any good.It's not a rule, but generally an incredibly standard thing to do in any business model. I'm sure Walmart and Amazon got really comfy where they're at by not increasing productivity right?
I understand why people are upset. I personally have found the writing to not be as good starting at the VERY disappointing Eve update. Saying that, expecting the game to go faster is idiotic because it clearly is not going to go faster. If it really matters that much then don't donate. If you don't donate then why do you care, it's a free product.
