...it just punishes way too harshly one bad game in dozens if not hundreds of games...
It is very rare to get punished off of one game alone out of hundreds; and if you did get punished for just one game, then you'd have to have flamed pretty hard in order to warrant it. More often than not, it's a streak of misbehavior that builds up to a punishment, not one-off instances.
...anyway I'm asking if it is at all possible to reach honor level 2 before the end of the season...
Short answer; no. Even the fastest cases of Honor Climbing went one checkpoint per week, and there's only eleven days left 'til season's end. That's not enough time to climb from Honor Level 0, Checkpoint 1. Would that there was any better news, but, sadly, you'll just have to do better next year.
...and how exactly does it work...
As far as I know, the Honor System works as follows;
As long as you're not being validly reported (be aware, reports can be validated for even low-key offenses such as defeatism, passive-aggressiveness, etc.), you gain Honor for the following:
- Playing matches (you will always gain a degree of Honor progress for playing matches.)
- Being Honored (the amount gained is small, but it's definitely a tiny boost.)
- Getting the Team Honor Bonus (it's been said that this in particular plays the largest role in Honor progression, so it's good to always make sure to Honor at least someone post-game.)
If you get validly reported in a match, though, your Honor progression in that match will be slowed, potentially even ignored, which can result in a much longer climb in Honor.
...is there anything i can do better...
The best advice I can really give is, play plenty of matches, put your best foot forward to be honorable (and no; you don't have to be a "cheerleader". Some light positivity and even just general chatting can be plenty enough.), and always make sure to Honor someone post-game, since the Team Honor Bonus matters quite a bit.
...is there any way to farm it...
No, not really. Considering that 2/3 of the potential Honor gains are ultimately up to other players (whether they Honor you or not, and whether or not everyone Honors someone for the Team Honor Bonus), there's no legit way to "farm" Honor.
Which is as it should be.
...exactly how much less does premade honor count...
From the Honor FAQ...
Can I game the system and boost to level 5 by constantly playing with a premade and honoring each other every game?
Nice idea. We had it too. So we specifically built Honor so potential exploits like this give you (and your friend) literally no benefit.
Basically, Premade Honors are worth zilch. I've seen it posed somewhere that they are potentially worth something, but even if it is a non-zero amount, it's still negligible, and piggybacking off of Premade Honors is effectively pointless.
...because the lack of information about honor and how it goes up is astounding this system has been here for years...
I suppose I come from a point of bias, having seen a fair bit of the Honor system explained here on the PB boards by Riot employees, but I still wouldn't say that there's a lack of information about the system. Is it all in one place where it's easy to find? Not really, no, but take a little time to look and you'd be surprised as to what you'll find about it.
