ok then, take someone into a hm fp who knows how to play the game but not the class you give them, with no gear, no rotation and see if it goes as well as if they were playing a class they played from 10-50
i can effect others though. the time spent playing 10-50 is teaching people how to play the class and the ac they have picked. To change after so long it completely changes how that toon will play from then on. Then that person has to take the time re learning skills and abilities. This could work except what if that person goes into to a hm fp or an op with no clue how the new skills work it hurts everyone playing with that person. Also not every shares armor and weapons. Example: going from a guardian to a sentinel you lose the ability to wear heavy armor thus you no longer have any from of gear or a shadow to a sage you can not use your weapons anymore.
honestly no one knows what the words GAME BREAKING mean any more. You know making it so the game can't be played at all. also saying its unfinished is kinda stupid for an mmo as wow is still unfinished then as there are bugs in that game that have been around for years as well as they are adding in new content to the game as well
