Are you sure you need such cards?
Why would they have to change the CP to 50? We're talking 8* vs 7* here. Plus, Panzers have a low cooldown which compensates for the high CP requirement. 8* dragons are at 25.
Aside from all of this, the real issue at heart here is that there's no way for anyone to evolve normal dragons without spending their lifetime doing so. Someone did the math before and it breaks down to about 5 years to have a chance at leveling a normal dragon's skill playing day and night non-stop. In addition, skill level for many cards, including full HP restore cards are next to impossible to level up and remains an unsolved mystery to the DE community.
So whether you change a card's skill level so it can be done, make cards more readily available to level existing cards (like panzers), or reduce the timeline for acquiring these cards, the end goal for the game should be offering attainable leveling to work towards, not 5 year scenarios such as this.
The III vs IV scenario is one small example of an existing problem without a workable solution related to skill leveling. And to Aro's point, the benefit of getting an 8* reg dragon pales in comparison to getting a 7* panzer and requires much more work. I don't think that's debatable.
