2010/11 era
clan wars- used to be packed and large clans fought in it (pure/main clans 100v100)
soul wars- wasn't dead content, although filled with bots you could still be able to play it. now probably there isn't even enough players to start a game in the worlds.
Dungeoneering was at it's prime, chaotics where the best weapons ingame and challenging to get.
Combat system wasn't complicated, and allowed many different types of pking.
Leveling, combat wise it was a challange to be lvl 138, all combat related stats 99. Now one can be 200 cbt and only have 2 99s.
The game wasn't dead, with around 400-600 players each world (2012) it was decent, now on eoc worlds max you'll find is ~90-100 players per world?
------------------------------------------------------------
Ep system (in my opinion as a pure) was something enjoyable when i was a pure/zerker/summoning tank (3 diff accs) because even if they didn't risk you still had the chance to get some decent loot.
When wildy was released it practically fucked my summoning tank. Lvl 34 with iron titan killing lvl 30s that drop maybe 100 chaos runes? while with the ep system i got loots resulting up to 10m (which was a shitload back then for me)
