Many players, at the end of the season, simply change classes to get better ranked positions on the battlefield, and often they have never played with that class, this is quite frustrating for players who have less favored classes at the moment, and play less , but who have been with them since the beginning of the season or the game itself.
It would be very interesting if the Battlefield was linked to a specific class and not to the player, for example, if he plays Tempest, which is one of the most played classes nowadays, and then wanted to change class, for example to Monk, one of the least played, the score should have been reset, since what he did was not with the changed class but with the one he was in previously.
Doing this would make the game much fairer, and put an end to the binge of many people who sometimes, with just 24 hours left until the end of the battleground season, simply change classes to take the position of someone who actually put in a lot of effort with a less favored class.
