I remember in the Live Letter is was mentioned they were working on a training area for players so MAYBE that might help some.
No. Pattern recognition is a skill that can't be taught by a game. It will maybe impart some basic responses to common situations, but attentiveness is something players have to develop as their own skill. I remember chewing out a guy for failing every single mechanic in an instance and he was like "Geez, chill man, I'm new." And it made me think back to when I was new to that instance and you know, I didn't make remotely as many mistakes as he did; because I started tracing common things in this game. Like how most DPS rotations are similar, or how if an attack name contains "gaze", you probably want to turn away, or how if a tank gets some kind of debuff with a number that goes up continuously, it's probably a tank swap in the making. Not a lot of people think like that. It's kind of like a problem old men have with computers or modern home tech. They can be taught how to operate one machine, but they aren't taught patterns that govern all the similar machines. Kinda like how "Learn how to operate Microsoft Word" is less useful than "Learn how to operate Windows-based software in general". You know?
I don't know how to deal with this problem from a game design standpoint, honestly, but just look at how progression in this game is. You spend 120 hours going from point A to point B to point A to point C listening to neverending drivel NPCs have to spout at you, occasionally defeating trivial monsters. Then you hit levelcap and a whole bunch of challenges open up for you that assume that by doing all that worthless shit you somehow learned that uptime is important for a DPS, how aggro management works, why DOTs are more powerful than single attacks as a rule or even something as simple as why you should be turning the boss away from the party as a tank. Except, oh wait, the game now expects you to know and excel at all those things because there's extreme primals, raids and all that stuff. Tabris is not wrong here.
So maybe the training area will help alleviate at least some of these problems but after playing this game for months I firmly believe that being a WoW clone will absolutely hurt this game in the long run.
But making you clear Garuda and Caduceus to do Bismarck and Manipulator is a bit disingenuous because... well, because of how this game incentivizes players. You're offering a large ladder in a system where even one step sometimes ends up insurmountable (the diabolical Bismarck?). If there was no duty finder, a situation in which you go into a town and shout for a party will still be met with indifference from other players who've got better shit to do than to run a challenging instance that offers no tangible reward to them. "So just find a party of people that are at the same level of progression" can be a very unrealistic proposition in today's online gaming.
Let me just underline this with one simple thing:
this game doesn't teach its players to use Focus Target/watch castbars. Twisters anyone?
