POT Loaders are 3rd party tools that some players use and usually get away with it, it is an problem, and I'm really sorry that you fail to see, that this tools are among any other programs that automate parts of the game, and has nothing remotely to do with skill and the use of macros.
1.This programs can automatically keep your CP at an level specified by the user, and can spam them in less then seconds, with normal macros can not do. ( can set miliseconds )
2.Having this free mind while your CP automatically stays at certain lvl, lets player to focus on many other things giving big advantage in PvP.
Not every player is going to reach, or even aims at the "High End PvP" you speak off, that's true, and at the same time the nature of how things go in this game. Nevertheless it does not change the fact that game should be kept clean of 3rd party tools on all levels of play, players are not equal in skill... And especially when we talking about the META.
For the sake of comparison lets take, Two players of equal skill and consider an scenario where they are equally geared etc. An player who is able to automate part of hes task in battle have clear advantage, and having more resource (time focus) to out maneuver the other player, who in comparison has to spend his time trying to spam pots and skills, a battle that he cannot win vs Pot Loader. Also consider for example same two players fighting with same skills etc, the automate pot will always win vs normal pot spam / macro, because of reasons state above. ( Point 1 )
Lastly, comparing macros and skill play to the use of 3rd party tools as you did is just wrong, sorry to say but that misses the aim of this topic, which is illegal software.
A simple reuse time on CP pot would fix this, that's all, that is if there exists no better solution.
My humble opinion.
