What skills do you think could be combine into other skills to reduce future ability bloat?

SE has shown that they have taken some notes from the progression of WoW over the years. An example of this is item level inflation and how SE is trying to slow that down in ARR. Another problem WoW ran into was ability bloat. Now WoW is a bit of a different beast in how it handles utility skills and what not but I think it may be something SE could learn from before they get to that point.
It has been stated that we will be getting more than 2 new skills and in some cases new rotations with the level cap going up. It has also been noted that some skills are being reworked.
With all of this in mind, what skills do you think could be combine into other skills to reduce future ability bloat?
Try to keep balance in mind but let us all agree we are not devs and so there will always be factors in balance we overlook.

As a DRG some skills I think could be tossed into other skills would be:

-Heavy Thrust: 15% damage increase for 20s
-Phlebotomize: 30 potency DOT for 18s
-Feint: 20% slow 20s (I often forget this skill even exists..)

I think these 3 skills could just be built right into the True, Vorpal, and Full Thrust chain.

-True Thrust now adds 15% damage increase for X time
-Vorpal Thrust now adds a DOT for X time
-Full thrust now slows for X time

What skills do you think could be combine? Keep in mind SMN is getting a full rework and it sounds like BLM is getting big changes as well.
