You realize that players like you have helped destroy this game, right? You're complaining about a grind? WHY?! Of every single game EVER RELEASED, this is the easiest and fastest to hit max level on. WITH ALL CLASSES. I would say "Go try Final Fantasy XIV", but if you consider THIS a grind, you wouldn't last five minutes in ANY other RPG, MMO or otherwise. You can easily hit the requirements to clear all the main content in two or three days... ONE DAY IF YOU HAVE TOP-TIER PSO2 GEAR (Lightweave/Ophistia + Guardian God Units). It is easy to get every class maxed in one week if you play often, two if you clay casually. This is the easiest and fastest game ever made in the genre (possibly any genre). FF14's TUTORIAL is bigger than the ENTIRETY of NGS! What is Sega's excuse? Better yet, what is YOUR excuse? You people who want everything fast-paced and you want it all "NAO!!!!!!!!!" are destroying quality in gaming.
There are much worse things in NGS. How about the fact it takes longer to get from character select to in-game than it takes even SWTOR to get from desktop to in-game? All the lag and bugs that happen at least a dozen times per three hour game session.... How about the crap targeting where hitting blue is hard EVEN IF YOU DIRECTLY HIT THE WEAK SPOT? And that is just the start of the issues! There are a million things wrong with this game, but what you're complaining about is not one of them. If this game was any easier, I'd quit on the spot. As it is, they have until the region update to fix ALL the problems or I'm done with Sega altogether.
I was so busy with the OP I missed what you said that literally made no sense. "Regular bosses take forever"? WHAT?! Pettas Vera drops in SIX MINUTES. If you mean Dreads, those aren't bosses, they're this game's version of "Elite" or "NM" mobs.
