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.
Sorry to see you feel this way. Allow me to address your concerns anyhow:
Several pools will be available initially, though these are not all official (i.e. run by Veil). You can find info on hosts through this thread or on Discord about other pools.
Why 25% of the reward to miners? If you're assuming it's 25%/25% to miners/stakers that's inaccurate, as mining is greatly favoured during the hybrid phase. 50% of the reward does not go to the dev team. That 50% is split between R&D, reimbursing the initial project development and launch costs (as there was no ico and will be no premine), funding bounties, getting on exchanges, and finally team and operational costs. You're right there are plenty of projects running without that 50%, but those have had icos, premines, or started with blue ocean advantages. As we see it, there is absolutely no point giving more to miners (they already get the lion's share) of rewards if said rewards have no hope of gaining in value.
