While the channel does play favourites, there comes a point where the celeb AND their fans has to take responsibility. I really like that Mint is being more vocal about what she wants but honestly I feel like its too little too late. She was complacent for too long and like someone else said, she doesn't have much to bargain with. Regardless of who fans want to blame for her poor results (ch3 favouritism, poor scripts, bad pairings, etc), as a business ALL that matters to the channel are results. Her fans complain, but that's really all they do.. where is the actual support? Mint and her fans need to show the channel she's worth more than what she's currently being given.
There was a period of time a few years back were she wasn't prioritising her career and looked disinterested, I remember her fans said that she was concentrating on expanding her business, and were showing off about how entrepreneurial she was, saying how smart she was for doing a business as being in the industry won't last forever so its good that she's treating is as a hobby. So its funny they now want to complain about the way the channel treats her, when she herself wasn't prioratising her career and didn't care about the scripts she was acting.
While she was doing what she wanted outside, Yaya, Kim and Margie (I mention them because I see them as being part of the same group that got popular together) were focused on their careers, picking up more scripts, expanding their fanbases, networking in and outside of the channel, etc. doing the work and putting themselves out there. Once they had a more solid foundation they started doing other stuff (businesses, Youtube, etc.) while maintaining their ET careers. Mint has been lukewarm and just all over the place for too long. Nadech is the same but he has a super strong fandom to support him and cover up for him. They're not just fierce online, but also in real life, they go all out for him in various way, the most important being by opening up their wallets and showing their strong purchasing power keeping him in demand. Mint doesn't have that so she can't afford to be coasting along, then start making demands when she's ready to take her career more seriously. She hasn't got the capital to do that.
I'm not saying she was wrong to branch out but her timing and the way that she's navigated her career has been really bad. Even now, although I'm glad she's started speaking up I feel like she's not going about it the best way. For example even if she wanted to take a step back from filming for school/ her business by not doing as many lakorns, she should have been even more picky about what she chose to film. Instead she didn't care, and honestly it showed. This is the time where even if she couldn't film she could have been doing events and networking in and outside the channel to keep her visibility up, to increase the chances of her being offered a good script, or put herself forward like Ice P if she found out there was a good one that would start filming.
