I know it was unbalanced, but if it was tweaked right it could definitely work. Nexon "fixed" it by lowering everyone's HP and now I remember Heroes and NLs completely sucking after that. The best part was it being competitive without any microtransactions that gave an advantage (except the lv180+ one, but nobody went there).
I'm about to go on a rant here, that newer PvP was HORRIBLE! I had a buddy who was a max damage Mihile, and he and this other highly funded F/P mage just kept 1HKOing each other left and right. It just goes to show that the max potential in that arena was disappointingly boring.
yoo pqs in general honestly the social aspect of maplestory was the best part
i think the game could be a lot better if they just buffed pqs and made mobbing only necessary if pqs were filled up. that way people could still fight over clicking into pqs and talk to each other at the same time
