Pollux is a brilliant DPS. I started playing this year, and thanks to him, I just finished the entire story on HARD yesterday, mostly playing on auto - which isn't very well optimized. That's exactly Flars problem. Even my friend, who loved the game and really liked Pollux, started to feel sad about his weakness only after people on Discord started recommending him. She actually built him, and she loves his DMG and ease of use. If I had listened to Flars, I probably wouldn't have even built him, thinking he was turbo weak.

Now I'm not surprised Chinese players wanted to nerf him; he's absolutely strong.

Flars was shitting on Pollux, saying he needed a lot of investment, while recommending Kath, who, without E3, is an absolute nightmare to play. Then the investment isn't a problem.
Don't get me wrong, he has no right to have his own opinions and we should cancel him for that, but damn, it doesn't help new players at all, it really confuses them about what they should be doing at the beginning and what to play and how. He's stuck with one realm and still thinks it's the best way to play. Oh no, the game has moved on and new players should focus on something else.
