It's not just about poorly or evenly distributed - it's about fairly distributed. Digibyte has/had a premine, Myriad did not. Digibyte apparently aggressively cut its emission schedule, although when I asked about it on their thread I was basically ignored and it seems non-trivial to dig up info on it; Myriad also reduced it's emission by a factor of 2x, a move that I wasn't really a fan of, but did so at a later point in its life, and I'm going to assume less aggressively than DGB.
Well, in the case of Myriad, it wasn't done to advantage early miners. The network seemed to make a mind of its own that 1 minute target block time was more suitable. The average block time was never getting close to its target. It had been gradually increasing from the target of 30s to an average of 50s+. This had been going on for many months. The reason was that sha256d and scrypt were being hit hard by profit switching miners. The algos generally had low hash rates, and large miners were mining up many blocks in a short time whenever the difficulty got low enough, then switching. Often blocks wouldn't get found on those algorithms for days due to the high difficulty and low hash rate. Obviously this posed a huge security threat, as well as being unfair for miners. The solution was to switch to auxpow on sha and scrypt. Then blocks started getting consistently found. Also there was a bit of a problem with Groestl finding blocks, too, which was fixed with the new chain selection algorithm.
Had the target block time not increased to 1m per algo, the new hard fork would have seen a sudden increase in emission by possibly 60%.
Basically,
the emission didn't get reduced by a factor of 2x. It was more like 1.25x, and at the rate things were going, the average block time could have been headed towards 1m without the hardfork anyway, which would have been very bad news.
In the very exceptional case of Myriad, increasing the target block time was actually the fairest option.I think this speaks to the level-headedness of Myriad developers, who, by the way, are not a foundation or company or any sort of organisation. They are a loose collective of people who have taken an interest in Myriad along the way. This grassroots nature sets Myriad apart from the vast majority of other coins, and is why I think Myriad will stand the test of time. Other coins will die with the company spearheading them, but the small Myriad community will grow and continue to live on. If you've been watching
http://myriad.nutty.one , you can see that Myriad appears to be growing. The peer wallet count averages in the 60s lately. Before the hard fork, it was usually in the 40s. Also note that there has been an increase in the average hash rate on the GPU algorithms by a factor of almost 2x. In spite of the fact that emission for those algorithms has halved!
