Well, I mean, that sounds like your problem right there. If you don’t even like the IDEA of Assist Trophies, then of course you wouldn’t be happy for one.
I understand where you’re coming from: being an AT means not being playable and if that’s the only thing you care about from Smash, then I get it.
But don’t act like that’s the only thing ANYONE should care about. I’ve always liked games with summoning effects. Calling in a powerful creature or another ally for a quick attack just always resonated with me. And I think Lip’s puzzle-based fighting style could really make for a single poignant attack and really brings to mind summoning-type mechanics to me. So I think she’d make a really great Assist Trophy concept.
My overall pet peeve with Assist Trophies is that, compared to overall summoning character aspect, they're, in the end, treated more or less as like cameo-glorified Pokeballs at best (though with more complex A.I and probably stronger too depending on the moves), and are all very random to receive.
They certainly belong on making Smash look more festive, but at the same, Assists feel also dumbing a lot characters' legacies down just for that and even anger some fans to the point of memetic status (like with certain purple wonder I know).
I also don't know what to feel about the fact that ATs also include the mooks from represented series as well. It kind of confirms the overall premise about ATs just being "whoever Nintendo-characters they find interesting to be messing around in the battle", where the fan-favorites not deemed playable enough can be comfortably thrown to as well. It doesn't make Assist-status look that much great (to me at least) in the long run - hence the "item"-comparisons.
Whether they get given new attention through this Assist-status, tends to kind of fluctuate. I think likes of Sukapon or Prince Sable (and probably by that extend, Lip) are fine, since they're from one-off games, so them being cameos in Smash is adequate enough for them - they are relatively easy to explore and learn about in fans' eyes.
But to those still popping in new games or even being asked for revivals, it gets much hairier when they have long-awaiting fans that now and then search, or even receive some of them being noted by Nintendo, and clamor them coming back to limelight in some way - with Smash Bros being best vehicle for that (Takamaru, probably Isaac, etc.)
On that end, Assist aren't really given much ways to have anymore presence in the game, or even series as a whole - since all focus is on,
*ahem*, the
playable fighters. The best you can see them item fights within the multiplayer, or single-player modes - which has me usually forget they're in the game. (
Though the less I'll be reminded of how Starfy's a complete joke today thanks to Smash Bros, the better.)
In the end, that's what they end up being - glorified cameo items that might have varying degrees of grown gaming community awareness, but to me, the concept itself isn't exactly "amazing" to write home about in the long run, instead being this generic, safe way for Sakurai to earn awareness points while also being able to dismiss on these fan-faves into "summon items" instead, despite the iconic moves and legacy & fan following they have.
While I know this wouldn't remotely fit to Smash Bros's nature, I sometimes can't help but think how we could have a system where you could use Assist like in Marvel-series or similar fighting games to dish out attacks or two, making them feel part of the fight in a regular fashion instead of being relocated to cameo appearances not - not only it'd probably mean less fluff-like mook Assists we see in the game to muddle up the glory offan-favorites to feel just "simple cameos" like them at times, but it'd also allow the fans of these characters still be able to use them in battle whenever they like, and have interesting ways of utility, depending on the character.
Just my views on the matter.
