So, I was reading this and well, decided to give my opinion:
I have a lvl 35 char, fully equipped with mystic and 1 or 2 legendary items, good bonus etc. I farm metins and bosses quite oki until lvl 75 without buffer, and could make an "average" farm out of it.
The thing is, progressing to lvl 75 or something higher/similar is pointless. The good items are crazy expensive and not only, as other people said, farming dungeons is hard if you have a tight schedule (Im at Uni), there isn't much to do besides that. Why will I lvl if I'll make less yang. Still, the IP block is kinda healthy.
This leads to other thing, boredom. Same farming method over and over again. Metins lvl 60, v2 and moonlights.
The market is plain dead and best way to farm is buying TEC, and that says all.
And now this is the part that will get this comment deleted. There are plenty other sv's with more regular updates, as in way more, and with a more friendly gameplay.
Every time I log in I see the same items in shops and the people either lower the prices, or just give up selling them, as they wouldn't profit.
Regarding the IP block more specifically, and why I think it's healthy:
Metin2 has been a pay2win game traditionally, as in order to change items, the place to find switchers is at IS. The thing is, it is a game that when designed was made for people to play in groups, hence the existence of guilds. The least healthy thing is the fact you can log more than 1 account or 2 at the same time, as it completely kills the need of cooperation is most cases.
I see a lot of angry people with the IP block because they use to farm alone with multiple chars and made profits way higher than they should had ever made. This lead to yang monopolies in the server. Same people doing dragon and hell runs etc over and over again, while the lower lvl or least equipped could only watch.
The is a reason most mmorpg's you can choose a healer, tanker, dps etc... character, and why cooperation is needed.
The sv lacks a bigger variety of dungeons for more levels, and more lvl distribution farm wise. That's the problem, and IP block is the start of a solution, but farm from being it.
