I don't want to be argumentative as you have your own experience. Mine has been different at WDW. I went to WDW before and after FP+ and I have not seen a big a difference on POTC and HM. There may be a small difference but I have not seen it as big as you have.
The link I posted to TouringPlans had a statistical analysis they did based on 3 million data points. And they said FP+ by itself did not make a big difference in wait times on average. Remember that WDW has seen growing attendance so not all increases in wait times can be blamed on FP+. TP just posted a new study here
http://blog.touringplans.com/2017/04/26/long-term-wait-time-trends-walt-disney-world/ where they said that the increased wait times seen receently appear to be caused by WDW staffing - not FP+.
In any case, it sounds like DLR is the right place for you!
