And its also a slap in the face for casuals. First, lest define casual gamer properly. The casual gamer is considered casual because of the time put into game, whether said time is available or just what they want to spend playing game, not because of skill level of game. Casual players are not lemmings or children that just play blindly and are just ok with hitting 2 buttons all day. Casual players are casual because of time invested.
Now, like previous poster has said, the problem with this game is that there only two ways to play. Either doing slow monotonous boring grinding or trying to raid. SE (and lots of others in this community) have a problem with how they perceive "casual" gamers. Casual gamers are not stupid. Casual gamers are not mindless zombies. Casual gamers are not just content with easy stuff. I consider myself a hybrid gamer. There are days when I have nothing to do and I can play games all day, hardcore. But also there is this thing called life. And not everyone is living the same one. So because of that, there are people that just can't put in the time to do some of the things in this game like relic grind. But also, those same people don't have the time to form statics, have time to be dedicated to certain times to play with others to enjoy end game content. Where are those people to play? The main problem with this game that many are having is the "time" you have to put in to do either of the two options in this game. I like to play all at one time as much as I can, but there are days where i only have maybe 1 hr or 2 each day for the whole week. So stop using the word "casual" so casually when talking about a group of players.
Now, I like a challenge. Time grinding same low lvl dungeon for hours and low lvl fates for hours for RNG is not a "challenge" as far a gaming goes. It has less to do with game skills and more to do with enduring monotonous boring stuff for hours, which many casual gamers do not have. Casual gamers are just asking for an increase in difficulty, increase in story/lore, increase in fun. All of you elitist think that if you are not hardcore, you must be casual. That's far from the truth. And the faster SE and the majority of this community realize this, the better the game will get.
