A new patch for an MMO is a bit like a present. At best, it can provide a number of new opportunities for fun and enjoyment. At worst, it can break several things you already liked and now have to replace. Aion has recently deployed the new patch 1.5.1 and, as could be expected, fan reaction is somewhat split on whether it's a nice present or the immortal pairing of socks and underwear. Certainly there isn't a major content influx, and the often-requested reduction of the game's grind has yet to be implemented, but there are still a number of nice updates and additions.
Leaving aside the bugfixes and optimization with only a mention that they should help the game play more smoothly all around, several instanced dungeons have been adjusted somewhat. Nearly all of these changes look beneficial to players -- reductions in difficulty and increases in reward, as well as added UI displays for important objectives. They've also added stealth-detecting NPCs to starter areas and increased several NPC health totals in an effort to curb destructive PvP tendencies. Quest experience at mid-to-high levels has been adjusted upward, rewards have been slightly improved on several quests, and level-difference experience penalties have been reduced. Last but not least, there's now more incentive to hold a fortress in the Abyss and work to defend it, as rewards are offered for defending players. Aion's fans aren't all happy about the changes, but it's best if you take a look at the changes yourself. Just remember that even if you don't like it, this present is unreturnable.
