I'm done with the game, haha.
The game is pretty good from levels 30-60, but after that it gets unmoored. Desolate, Feralas, Ungaro Crater, and the Winterspring are great zones.
But after level 60 flying gets unlocked and it kills the epic scope of the game. Flying basically eliminates gravity as a factor in the game and it disconnects you from the game world.
Furthermore, after level 60 there is an insane amount of inflation in everything. My damage from moonfire went from like 2k to 10k in two levels. Gold coin is nearly worthless. There is no point in copper or silver coim because gold is so worthless.
There is no more spell interrupt on melee hit. Abilities are learned automatically and no visit to trainer required. There is no point to first aid skills because regen happens so fast.
So as to private servers, I know Elysium/Nostalrius is up. Are there any interesting private servers which have a very hardcore ruleset? Like, I would like to see stats squished relative to vanilla.
