the devs have to do something about the difficulty hoppers. we have just seen a block of more than 1 hour. this is something inadmissible. the block 258218 was the one that took more than 1 hour to get solved. why in the hell i would like to mine a coin where someone just collects and makes me mine at 30-40-50% more difficulty than the network really has? i love this coin but we begin to see signs of shitcoin blockchains here.
Agreed, i'm also frustrated by the high dispersion in block solve times and would like to see this improved. Thanks for pointing out something that i'm sure has bothered plenty of others. Sometimes i find myself staring at the block height waiting for a confirmation and feel like i'm trying to make water boil by staring at the pot.
Although some ways off, the blockDAG scaling research we're doing is a promising solution to tighter clustering of block solves, which is also important for reducing pool concentration. Still, we should do something sooner either way.
