First off, let’s get the default “online is bullshit and points are worthless” statement out of the way.
Ranked has one glaring positive that Endless doesn’t: it tests your ability to adapt quickly. In Ranked you, on paper at least, get one shot at a player and then he/she is gone. You have that one game to outplay them and their potentially wonky bullshit. You still wind up with some regular players if you play long enough, but you will always get some stranger playing in a way that may not fit perfectly into your style of play…and you have 2 out of 3 rounds to figure that play style out. That’s even more brutal than a tournament setting, where you at least have best 2 out of 3 games to figure the person out. Bitches in this mode will quit before the match ends while they were navigating to send you a PM on why you lucked out.
Endless was where I saw a lot more solid play from the online community. If you play against people around your skill level more than a handful of times (not points level, but legit skill level), they should eventually adapt to you, which forces you to adapt to them, which forces them to adapt to you, etc, etc, etc. Being able to adapt and adjust strategy, IMO, is the end game of learning systems/match ups/footsies/random wankery. It also takes experience, which hey!, that’s what Endless provides. Bitches in this mode will stick around and work a room of players all day long, but will leave the second someone wanders in and squashes their ego. The absolute worst of the two IMO (see P.S.). Also likes sending PM’s on why you are an inferior player, forgets that no one asked.
Shorter version? Endless = panel beating your ability to adapt your strategies. Ranked = Let’s see if you can genuinely adapt with those strategies quickly. They are both lag prone so fuck playing online, so it is preferable to find a crew to play with offline in your area.
P.S. Losing consistently while trying to learn “why” is okay. Being honest about your skill level, that you don’t have to win every game, beat every person and that you don’t know everything about a game will keep you mentally sane (just as long as you don’t take it to the point of having a defeatist attitude). Losing consistently and making excuses, however, isn’t okay. Everyone gets salty and starts blaming their stick/lag/the character/etc. In the end you have to take a deep breath, be truly honest about why you may have really lost instead of sparing your ego and move onto the next game. No one has a perfect win record. Perfect loss record on the other hand…
2 cents. Spend them on something nice.
