(...) sometimes you fall into such a trap that you do not see (...)
I feel that everytime I run rofl without a scout in party
That's a very objective statement and so true on so many ways. I agree on most points (can't speak about rogue for example) and one of the best choices would be a split into multiple class specific sections / sub-forums, as I already suggested multiple times in the past. The major problem in the balancing thread is, that - as you also mentioned at the beginning - most very important posts getting lost so fast and spammed away. So you need to activate your entire guild/friends to like the posts to make sure, ppl see it... which is just unfortunate.
Just some quick notes from myself on that topic... breifly... at least I try to keep it short
Balancing of magical classes
The season thing is a good comparison, I also see something like that happening with the mages. I stopped playing primary mage, because I wanted to get rid of changing my subclass any 2 weeks to deal the most damage with it. But however, I still find myself changing my class any 2 weeks, because another OP class is popping up. Nowadays it's the druid/rogue and warlock/scout which are most overpovered (imo), maybe also warlock/warden can be included since that class is too easy for that huge amount of dmg it deals, which is far away from any other magical classes, even if it's not the strongest one.
Balancing of Tanks
Another big problem is that there is literally no balancing of tanks. I appreciate the change of Warrior/Knight some weeks ago, but that was a single adaption, which didn't really make the class viable, just a bit less worse than any other tanking class. At the moment I'm seriously asking myself to sell my entire plate gear and buy a chain one, because I coult tank equal as a champ and additionally deal damage with one single buff change. Also I would finally be able to play event at b1 in rofl as a tank, since my plate has not enough patt on it... a chain dps gear would have and is equal if it comes to tanking! I mean, maybe boost the champ's damage in general, nerf the op champ/mage and cut away that shield form, which is just broken overpowered imbalanced by far. Maybe let the champ/knight as it is, but also require plate armor to be a viable tank.
Atm you have much better defensive values as a champ/xxx in a dps chain gear than any warden/warrior, warden/knight or warrior/knight tank in plate armor out there. Even some knight-classes are having worse values than dps champs! I'm glad, my guild still accepts me as a useless plate armor-guy, because I use to play utility classes with a lot of crowd control, but having a knight/rogue or knight/priest in a raid would be a waste of a slot these days, which is a shame! Let a tank require plate armor or at least adapted gear for being viable as a tank.
In terms of aggro per second, we better don't talk about, that's another issue, but not relevant at the current (still beginning) state of balancing.
The current state of balancing...
...is literally at the very beginning. Just a few months ago we got the new warlock combinations, that rerolled the entire meta for magical classes and literally busted it. Additionally we got so many rebuilt classes in the meantime, that are partially op (r/s) or totally useless (s/wl) compared to the most others. Can't speak about chain and lether classes, cuz I don't play them. But guild mates told me it's not different at all.
I agree on the schema Merkur suggested...
Quote from Merkur
...and think, this entire thing - as it is atm - needs a huge rethinking in terms of an order of the entire process.
I think, the current way with only 1 balancing thread is the best wrong decision that was ever made for that process. It's hilarious how some ppl try to make their very own favorite class the very best, since all of us are pokemon trainers who want to finally beat the champ. In my eyes there are 2 options: Either close the thread and don't care about community feedback or separate the classes just like Merkur suggested above. Only problem I see there are those special classes like warden/druid, scout/warlock or warrior/mage, because those are magical classes with originally physical main classes. Same relates to a lot of others, but that shall be just an example.
BUT I don't wanna make the entire process a bad thing, because there was so much time invested and I appreciate many of the past/latest changes. So it's not everything lost already. We still have many viable new classes, even most supporter classes are very interesting and make the current meta different to any server I ever played on. I see a huge potential there, if you do the stuff right. I still have hopes that this comes to an end some day, but I think, it's still somewhere at the beginning. I think, someone needs to find a clear path and some sort of structure in that chaos and you will do fine then, I'm sure.
