Yeah you already know what I'm going to say. Fix wifi please guys. I may cheat a bit here when it comes to my list, but really I can't think of anything but the online that is problematic, plus I came up with a very detailed list of everything that drags it down for me.
1-Visible tags and the return of taunts: Yes yes, I've heard the defense already. However you're not really protecting anyone by hiding tags, like "oooooh he showed a bad word!" I mean come on, people that can understand what a swear means have already heard it before, you're not sparing anyone's innocence or feelings. By the way, if you're playing Co-Op and your teammate is the same fighter, or heck, even similarly shaped fighters with similar color schemes (literally any FE character and most normal humans in general) (by the way I love anime swordfighters please stop with the hate) it gets really hard to tell each other apart when one of you is Fell God1 and the other is Fell God2 (oh and sometimes the numbers aren't even there so you end up having the same tag). Similarly, removing taunts during online play is not the way to go because, like in the case of hiding tags, no feelings are being spared. I can't tell you how many people I've t-bagged at this point probably in the upper hundreds. I'd rather be using the BM function that was specifically added into the game but apparently those are too offensive or something. Oh well, maybe they'll add a shooter game protagonist and then the t-bagging will be much more immersive.
2-Elite Smash and related things: For starters I don't think GSP is a terrible system. Sure, it's obnoxious how I gain about 100-300 GSP per win and lose about 1,000-3,000 every loss (not an exaggeration by the way) but whatever, once you're near the top it's supposed to be harder to climb, I get it. The problems arise in that GSP is character specific which is the reason you can't switch fighters between games. Yeah, change that. Just make our new overall GSP what our current highest is, it's a better indication of skill and it's not like anyone but myself will be hurt if I lose by sandbagging as a fighter I'm terrible with. Also, Co-Op online play deserves Elite Smash ranking as well. I play it a lot more than most of you probably do, and let me tell you, most of the people there are so terrible that my teammate and I start to sandbag on levels comparable to Isai in Melee. It gets really boring crushing the life out of bad players the 1,000th time in a row, though I'll admit it's better than constantly losing.
3-Battle Arenas and rules: That's right all three of my grievances are related to online...a real shocker, huh? Well let's get something out of the way first. Battle Arenas should be able to be entered Co-Op, period. The play with friends option had it in the last game, and since battle arenas have completely replaced private lobbies, it's only natural they inherit this...it's a pretty simple feature. Furthermore, let us practice while waiting alone in an arena, it gets pretty lonely when no one is around. Also let us switch fighters (and preferred stage if applicable) without having to exit the ring, I'd rather not lose my prestigious position of being in the ring just because I don't want to play as the same fighter 30 games in a row. Finally, preferred rules online should be more in-depth. Allow us to pick exactly which stages are legal under our rulesets instead of "only battlefield, only final destination, everything, or everything but with hazards off" because let me tell you, I'm sick of Battlefield, I'm sick of Final Destination, and I'm sick of dying to stage hazards. Oh and while you're at it, let us turn team attack on so that double projectile camping is even less viable (lol good luck now Belmonts).
Ahem, that's all, probably. I didn't want to address balance because as much as I hate Inkling, Ness, and all the other annoying characters, I still don't want to speak for what I said good or not for now. This game is almost flawless, and 99% of its flaws are in the online play, in which it's pretty flawed unfortunately. I think I went sufficiently in-depth with all of my grievances with online play, and I think all of my solutions and suggestions are not only reasonable, but necessary. Let's just hope someone important sees this.
