18 MPH is fast. It doesn't look fast to us when we watch cars from a distance, and it isn't close to fast enough to outrun a thrown dagger, but it is right about the speed that a top tier NFL RB hits in the 40 yard dash. Try asking friend to drive right by you when you're standing at the edge of the curb. It looks a lot faster than you may think... especially if you imagine it being 20 times the size of the car... Plus, some spellcasting dragons may look at longstrider, expeditious retreat, etc... to allow them to cover ground even faster...Personally, what I feel needs to be fixed isn't the concentration mechanic, but the dragon's fly speed. It should be doubled at least (The fastest a dragon can fly with a dash action is 160ft in 6 seconds, which is 18mph) ...

It seems that 5e has created a new variant of this same problem, that a certain category of fights are dull because the optimal tactics are both boring and obvious once you have figured them out. Obviously there are ways to mitigate the issue, like drop Boots of Flying into the loot; but that is an implicit admission that Celtavian's point is correct.
The general idea of the concentration restriction seems like a great thing to me. But it may be too all or nothing and too inflexible for making the game be as fun as possible.
There are only two ways that I see to overcome this. Throw tougher foes at the PCs. Or. Pre-plan encounters with specific tactics, environments, and foes that make problems for the PCs. The former is easier to do. The latter takes a lot more effort and I must admit that I do not always have the time to put in that level of thought and effort.
Whether its an issue or not is up for debate. I don't really think its that bad, but the thing to watch out for is NOT character vs creature, but how some characters can overshadow others with minimal effort.
