Shame on me for sleeping. I should have known better, he who plays Lineage shall not sleep.
On a serious note, since the XP event ended, server population (active players) has been declining. Most people went into afk macro mode or offline waiting for better days mode. A lot play different games or event some illegal servers. And you can't really blame them since the wake up call after XP event was brutal.
Since then we had:
Halloween Event - which was cool, pumpkins gave good buff and haunted chests had good content, worst case being 3 roses or freya scrolls.
Ultimate Jewelry Boxes - overpriced and really bad contents for a box. A very expensive event catered to a few people.
Lara Gift - Also known as how to artificially increase server population with online boxed chars. The gift rewards were a lottery with no real prize. The Lara buff was let's admit it, almost useless. Funniest thing was the Lucky Growth Scrolls which gave 30% xp in vitality mode when no one had vitality anymore.
Snake Cards - It's a cool concept but in the end the rewards are not making me think I MUST get them. The 500 Shots reward makes the whole event be skip - able.
Night Market Coins - Good sale event, so good that Ncoin price exploded and thus the sale became like the Ultimate Jewelry Boxes, catered to a few. In all fairness the event crashed the market (what market some may say) a bit and items got cheaper.
Black Friday - This is supposed to be the biggest sale of the year, how come the summer sale was a lot better than this ? Selling 100 destiny packs only was only going to cause a negative reaction. The destiny pack keeps people engaged in the game, so a sale on it was a good idea. But why 100 at 400 ncoin, why not just unlimited (1 per account) at half price (1200 ncoin) ?
