Every game I have played, the gaming company nerfed stuff. I absolutely hate that. You buy/earn and work your rear off to get better, just to get nerfed. Every game, nobody and I mean nobody is happy getting nerfed.
Yet this game, all kinds of people are wanting others to get nerfed. It makes no sense.
To me this is just crying. Waaa my character isn't as strong as someone else's. Waaa I don't have the strongest character in the game. Waaa. Please nerf everyone else to make me feel better. Waaaa.
I fully admit that there's a lot of details to this topic but no game is going to be totally fair. Especially with people using multiple accounts and others using bot accounts. Then there's hackers.
Also, in this type of game each character is going to have strengths and weaknesses. Some characters are just going to be stronger than others. Fighters will always do lots of damage and have great health. Mages will always do tons of damage but can die easily. Priests can heal but can't do tons of damage.
Find a character that fits your play style and stop worrying about others. If your character isn't the strongest, then make it stronger or play the character type you think is the strongest. If you're a scout then be the best scout you can be. Try for being the best scout in the game. Forget about everyone else. So what if someone else does more damage than you. So what if someone can heal more damage than you.
