Haven't played L2 in a couple of years now and as EOGamer L2 is completely inactive due to no staff, I can't get any input from there.
Is the game enjoyable if starting over as a 2 man team?
Is it enjoyable non-pvp, exploration-wise?
Long time ago, you could enjoy some pretty awesome places just at relatively decent levels and many of those became high level places. Is there anything enjoyable now when leveling up?
Is the game playable without adena buying anymore?
Are there stille enough players around to have fun?
You get gear along the way now that the game provides at certain levels as well as doing quests. Attain a mentor in the game that is active and you have buffs most of the time that help tremendously. There are a lot of new areas to explore and I have to say after taking a brk for quite a bit of time and coming back recently myself... I think the game is much improved and still fun to play. Although the adena and drops seem to be reduced a bit... daily quests can still gather a nice sack of gold to sustain play....
And leveling is ridiculously fast compared to last time I was in game(4 yrs ago)
