I personally kind of hold a grudge against the Tales of series due to two reason one is... Very bad experiences with certain fansI shall not name whom I have met in the past.
I've had my fair share of issues with Tales fans - I don't consider myself one of them, so I'm not surprised that we disagree on a number of things, but I've met some really silly people during my time in this fandom. I don't see why that should impact my - or your - opinion regarding the character's inclusion though, considering that every fandom has its share of nutcases, and doubly so given that the Smash fandom isn't exactly a bastion of reason and civility itself.
The other biggest reason is because I feel Namco has been using the Tales series too much in recent years. Yes, Pac-Man is also in Smash but they never even bothered to touch up on what a lot of fans wanted the character in for in the first place - He had nothing from the Pac-Man World trilogy. Yet they bothered to represent Pac-Land oddly enough which is even more obscure and arguably forgotten about. Not to mention Pac-Man himself has barely been used at all in recent years save for casual mobile titles and a cartooon reboot with tie-in games that were almost universally hated by fans.
From what I've seen in interviews, this is far more dependent on Sakurai than it is on the developer, and while I'm far from happy with Sakurai and the directions he tends to take, one thing I can't deny is that he tends to put thought and care into character implementations. Tales
is overused (primarily because Namco knows that it's a cash cow, and it's probably the IP with the most passionate fanbase and the biggest whales), but Bandai-Namco is a massive company, and these two franchises are done by different teams that largely operate independently of one another.
Could Lloyd's inclusion in Smash theoretically offer Tales exposure to a new market and cause Namco to push it harder and/or prioritize it over other IPs? Sure, but as we saw with Pac-Man in Smash, Lloyd in Soul Calibur, and Yuri in PXZ, chances are that they'll simply carry on with business as usual. History shows us that Smash representation is unlikely to affect their plans and the way they view different characters - like it or not, Namco views Pac-Man as a series that offers them more value in the mobile market than on traditional consoles (though I'd argue that this could simply be a trend within Namco itself, given that Tales has been flooded with mobile titles as well), and Lloyd joining the Smash roster isn't going to change that.
I also do have that mindset with not being into swordfighter characters or those with the typical "JRPG"/Medeval Fantasy aesthetic, But I don't want to say anymore about that as I have a feeling I'll be ripped apart if I went on why. ((And it's not just because I support a different Namco character, I just wish Namco wouldn't ignore other parts of the early 2000's they were known for. I consider those days their glory days.)) Hopefully at the very least Pac may go through a revision to have the Butt-Bounce added to his moveset. [preferably as a d-air]
We're not talking about a character like Pac-Man who has entire generations of consoles and dozens of games to draw material from - Lloyd has only appeared in two mothership titles, and he's fairly consistent throughout. Sakurai wouldn't base Lloyd off of Soul Calibur or Tales of Asteria, he'd base Lloyd off of his actual origin games, because those are the main titles in which he has actually been fleshed out, and the mechanics in those particular games - i.e. the arte system - would, alongside Lloyd's build, render him a very unique character not only among the sword fighters, but in the cast at large.
Also, No offense. I literally only played a bit of Symphonia on an emulator before I got bored of it and quit. But from what I heard about Lloyd's actual character charisma? He sounds like he could potentially get on my nerves in general. At best/worst I heard his personality is akin to that of Naruto.
Tales games are all about character development - their whole schtick revolves around presenting a fairly cliche setting with cookie cutter characters and slowly developing those and flipping them on their head over the course of the game. Judging Lloyd off of a playthrough that didn't cut into the meat of the story won't give you an accurate picture of what he (or his game) are like.
