It's far from perfect I admit. But things even out towards the end, actually - rangers are considered bad after level 50. There is a definite problem with early level scaling.
As far as getting banned for bug reports, there are numerous threads, and even a compilation bug thread endorsed by FC, so I'm unsure what you're talking about here.
Level 40 is actually when things begin to get good. - plenty to do in the field of the dead and tarantia noble district... Level 50 things get to be a bit iffy. A decent amount of quests, but you may need to grind a level or two; which is while quick - supremely annoying, however if you're on a pvp server If you're on a PVP server, cistern is pretty good fun and there are literally a ton of quests to do in there.
Also, it's my understanding that the only things that don't work are the base stats, stuff such as +slashing damage and the like still works. Not excusable by any means; but not as bad as you make it out to be.
I don't know, I have a feeling once I reach 80 I'll get bored with this game, but since I like the combat and the ideas I'm willing to give these people a bit of time to get their act together; but it is painfully apparent that this game was released far, far earlier than it should have. I still enjoy it, however.
Except Rangers basically one shot every class in the game except Guardians... Nothing kills Guardians. As a Necromancer I quiet literally cannot ever kill a Guardian that is 10 levels lower than me. My damage output is way to low, I have no where near enough Mp and the Guardian regenerates more Hp per second than I am doing damage.
And, I did get banned in the forums, for posting a bug report in a bug reporting topic, supposedly for life (though I was unbanned the next day) and was never given any reason for it.
Also... Level 40 is when things get good...? So the fact that there is nothing worth doing and the number of quests you had went from 30 more or less all the time down to 5 or so is some how better? By level 50 it is 20% quests and 80% grinding.
As for level 80... My advise to you is to not bother trying to get to it right now. There is quiet literally nothing to do. As mentioned, stats don't work, so by extension the majority of equipment does not work. And even stranger is how poor most equipment is. A level 80 super rare set of armor that could take you weeks of grinding to get can quiet literally be worse than the suit of armor you get for completing the Tortage storyline (I am not joking either). It is quiet common for the common equipment that is sold in shops or the stuff most every humanoid drops to be better than the super rare "end game equipment".
And honestly... The game is lacking most of the features it boasted about. Even though the case says "ENHANCED FOR DIRECT X 10" the game does not support DirectX 10 yet and supposedly wont until the end of the year. (Where I live doing things like this is actually false advertisement and a crime, if someone reported Funcom to trading standards they would face massive fines and have to recall all the games they have shipped and reprint them to give out truthful information.)
So yeah, my advise is for now to avoid the game. It is lacking half of the things it should have, and the things it does have are either bugged, don't work or seriously unbalanced. Wait until the end of the year, hopefully they will have gotten their shit together and have a game that is worth playing.
