Getting to the new deep dungeon is going to be inconvenient, because you can't just simply fly all the way to the Crystal Tower entrance.
Instead you have to go to the little gate, and click on it every time just to get there. Instead they should extend the flyable path of the zone slightly, and less us use flying to get there a lot faster.
It's not so much that there is a gate, its that its in a winding path that can be kind of confusing at times depending on your mental energy. Just saying, but this little fix would go a long way. We know it's not going to be this way at launch, because during the live letter, we saw Yoshi P using the gate, and not showing off the new mounts in that little sliver of the map.
