I'm pretty casual myself, I simply lifeskill or grind like 1 hr max a day. Although it may take longer to save up for items, you can reach your goals over time. It is not too hard to maintain a routine and earn a certain amount of silver a day till your goal.
I play since the beggining quiting a few times. Season and tuvalas are great for new players to learn the game and enchants. But meanwhile ppl are grinding high end spots making 400M an hour. People at intermediate levels can't benefit from season or high end spots leaving us in the purgatory. Enchanting system is also unfair making only 5% lucky ppl benefit. Maybe im frustated i grind a whole week for the potion and didnt drop a piece and broke 4 tri ogre rings making me a noob due poor luck. I feel im two years of grind behind. Maybe i need to afk fish all year or just quit the game entirely.
What you are describing is not casual, but lazy. You apparently expect fast progress with little effort 'in a hardcore grind MMO'.
rng is gonna average itself out at some point, everyone who has played BDO for a long time has experienced the feeling of RNG just fked me and im a noob due to poor luck. break past that point and youll have your success, to be completely honest it is hella easy today to get to a decent AP level. there were times where you havent gotten anything decent via season servers or events.
WRONG
The amount of attempts that a person could feasibly do on the important items is exceptionally limited. In the case of accessories and FGA equipment you will NOT have enough chances to average things out.
What you are stating would only refer to lesser items like PRI/DUO.
