Completely agree, that specific "plug in" literally changes one button on your skill bar into another completely different skill if its classed as a follow up combo, It literally automatically manipulates the skill bars and the slotted skills, irrelevant if it makes things easier or not and still requires one button pressing as some are arguing, it is still automatically manipulating gameplay through 3rd party software which is clearly an advantage and clearly breaking ToS

Using 3rd party software to manipulate gameplay is against ToS in most games. I know for a fact one WoW player and addon author is currently working adapting an addon from wow that lets you put you whole opener onto one button, you can literally put any number of skills into it and it will automatically skip skills on CD and have automated priority orders.

If things like these are left to get completely out of hand we are eventually and inevitably going to end up exactly like WoW
