sorry slow reply!
BDO is alright, I'm playing with TKG guys but not in TKG guild, we joined another one as there was only about 10 of us. ESO is still their official game, but i think we'll be moving to crowfall when that comes out.
It's a weird MMO, it's very time consuming if you let it get that way as there is so much to do. People get easily spooked by the "complex" systems, but if you do a little reading you work it out pretty quick. I've been playing since launch and only think i've seen half the game or less, it's rather big. It's korean, huge grinding, your time is the currency in this game.
I find the combat really fun, have only done a little bit of world pvp but not much of that stuff has been implemented yet. We are playing catch up to the korean version atm and just got a new class. All the expansions/content are free. Has a cash shop that isn't to bad, it has advantages but not really anything that will help you in combat. I don't consider anything on there good value for money really so just avoid it. (except the pets that pick up loot for you)
