I haven't tried Dungeon World or Strike, but ii think they're both definitely worth looking into. Out last combat in 4e took hours, and it ended with a lot of frustrations. Some of that was my fault, some of that is the die rolls. The rat swarm was a bit large, but if the priest doesn't get minions to blast he gets cranky.

With 5e, I actually have more experience playing than the rest of the group, and I want to take advantage of that. I'll miss the 4e online tools, but they don't work on Macs anymore. I'll be exporting all my characters off there this month.
