I have been enjoying the game a lot, even with adjustments away from hard mode.
I play a dwarf rogue (no alts), level 26 at the moment. I enjoy the fact that grouping in the game means something, and that you have to work together to accomplish things in the game. Learning about how to use expose and off-balance for those that can close those, as well as exploiting an open gap, make working in a group much more fun. I also like that you basically have to choose your skills based off of the group makeup and/or content you are going after. You actually have to think about what you are going to do and coordinate with others on how to maximize overall group dps, debuffs, etc.
While there are those people that love to solo their way through content, I am not one of them. I like being group dependent, hanging out with people. I am sure if I followed along with the min/max guides on Discord I'd be performing at a higher level, but that takes away from the fun. I don't play to have it be a second job, I play for the socialization that the game provides.
As for in-game experiences: Being a rogue, I get to go to places that my guildmates can't (I am the only rogue, lol). I like lurking around Hanggore, Mad Run, and HC. I sneak around EP. Sure, I am looking for loot chests, but I am also learning my way around so I can guide my guildies when we get ready to do the content. I watch groups in Hanggore taking on regular and named mobs, seeing how they handle pulls and such. Sneaking around gives me an opportunity to learn. My core group is usually a dire lord, a cleric, and whomever else we can pull in to go adventuring with us. If we don't die at least once a day, we aren't adventuring right.
