Free to play mesmer not viable?
To put it bluntly: No. And every other profession is in the same boat.
While the elite specialisations were supposed to be horizontal rather than vertical progression, in practice at the moment having an elite specialisation is still behaving like a straight-up upgrade almost regardless of what you’re doing. There are signs ArenaNet is recognising this and is buffing the core up while nerfing the worst offenders in the HoT stuff, but if so they’re taking the slow and cautious approach.
Mesmer is possibly one of the professions where this gap is smallest, in fact.
People don’t hate Scarlet like Game of Thrones fans hate Joffrey.
They hate her the way Star Wars fans hate Jar Jar Binks.
U can still be vialable, U still bring the same utilieties like with chrono. Good option agaimst chrono is signet of domination and pistol for stunlocking. They do not have many stunbreaks
In my opinion the biggest problem for core vs chrono is continuum split. They can essentially doubleshatter or double moa, double stun, double kb, double phanta summon – huge disadvantage and if used correctly it shouldn’t be possible for the chrono to lose vs a core mesmer.
Although you’re at a disadvantage in most cases it is possible to be competitive without it.

The video is actually worth the time to watch due to the OP taking the time to edit it and make it enjoyable, but the main takeaway is the fact he made legend using a f2p power shatter Mesmer.
So regardless what anyone else says, it’s possible to play ranked with core Mesmer. But is it advisable? Not really.
