A promised single pool launch (100% of the hash on a single pool...no bueno) and 50% of the rewards to "fund" the dev team seems like a disaster coin waiting to happen.  Miners need a reason to mine and 25% of the reward, with the current prices, isn't very motivating.  There's many very successful projects that run just fine without a 50% dev fee.  There's also many that fail with a much higher dev fee.  A high dev fund doesn't substitute for a properly ran project.
