This is wrong, every class should be able to play both pvp and pve, have advantages and weaknesses over others classes, it's called balance and yes it would be easy to just throw some changes without thinking deeply about it and what could be affected by it.
Doing what you suggest would imply to remove bind from ccbd rewards, for the simple reason that a pvp class or even a pve class such as dw is not going to make it or will be excluded, pve is not just farm, actually farm is the less i care when i think on pve, dungeons and ccbd are the real thing.
umm...The disadvantage of Fighters compared to PvE classes was that they sucked at it. Naturally cuz FIghter is a 1on1 DPS class made for PvP purpose. But ofc Fighter was still useful in Dungeons, especially for the Boss fights cuz it's a DPS class. But that was not enough for the die hard Fighter fanboys. They wanted to be pro SSJ Goku and also be able to farm outside of Dungeons. Just too lazy to create another class for that.
*Using Fighter as an example. Not hating them. So don't even try me @noobishFanboys
Also what Haly wrote. You could farm with fighter easy enough doing 1on1. That's how i farmed with my PvP SM back in TW. Just kill 1on1 but fast. Easy. But too hard for the kids here i guess. After all they wanna be Goku/Vegeta/Trunk and wipe out everything like PvE classes do with AoE skills.
The problem is you can never balance all classes to the point where all of them can do anything. They were not designed for that purpose. Forcing them into what they are not made for makes the game sh*t. You buff a certain class for something it's not meant to and it might end up being too strong in both fields (*cough* Ulti *cough*) since you take other classes to compare with. That's why the balancing in DBOG fails so hard and we will never have a good balance. It got destroyed. Back to the roos, little adjustments here and there and it's good. But y'all can chill. I'm 100% aware that it will never happen. Too many wrong ppl on here that just wanna have fun instead of having a good game. Y'all safe.
Now excuse me, gotta go spam Burning Attack with my SM. Just kidding, would never make a PvE Swordsman lmao. THat's against nature...
