Slow confirmation is going to be a thing of the past very soon. One needs to be patient sometimes however when sending payments over the network
It's normal before and still sometimes happening, there's a congestion so if someone is not too patient to wait for his transaction to get confirmed then pay better fees. It's the only way to avoid the slow confirmation of the miners, once you have set your fees to higher priority you'll be in the queue immediately and wait for a couple of minutes that will be confirmed. Sometimes paying higher fees is worth it when you're in a rush.
