On the part about Millia and Zato making things boring, yeah they do in a way but its all in perspective. Part of that perspective is how much you enjoy the game and how much you enjoy seeing high level play. If you do then you will look past it. Or maybe you won't as is the case with more casual folk. Hey! I am not dissing casuals this time around. In fact I am trying to partially agree with them. What I mean is that while fighting games can be loved by anyone, and should be, a lot of people and not just casuals but mainly them will complain in every damn game you see on "too much of the same damn characters every year" and honestly it makes me cringe. Look, if you do not like top tiers that is totally cool. I love so many characters that are low tier, and few top, and everything in between. That said no matter what you do there will always be top tier characters and that is a fact. Balance is an illusion, a good illusion to follow, but it will never fully exist unless every character has the same moves, health, hitboxes, etc, and thats boring. Thats literally just playing Street Fighter '87. Yes, its boring sometimes but it does not make the game any less fun and certainly no less hype. I get it though and I LOVE seeing uncommon characters of said game in high level play to.
Sorry. I hope I did not take a word or two from Dreiko and go into the totally wrong direction. I just see all the "same character" whining too much and get tired of it and while I have no idea what XrdRev is like beyond wanting to play PumpkinBooty I do remember Millia and Zato being top of the previous Xrd with Faust somewhere trailing behind.
Regardless forget about Xrd, or anime fighting games in general and please everyone reading this thread look at the overall picture and remember tiers will ALWAYS be in competitive genres and that is okay. You do not have to live by them but it is always good to be aware of them and tiers will not stop you from having fun. In fact for the average person it might make the game more fun knowing you beat your opponent's top tier character with your lower tier character or in a top tier mirror match you won and made it clear you are the better player with that top character.
