I am almost in the same situation as you, just played warframe for an year instead of wow.
Started here at the end of may because I do not like when my chars get wiped or servers get closed. In my mind the “Classic” meant a lineage2 experience like in C4-C5-C6, however this classic is a different game.
- The normal grind progress is really slow after lv40, so they added daily quests which rewards 1-2-10-20million xp scrolls but not SP.
- Events are OP AF, if you have cash to throw about, you can be king of the hill, Since the game is f2p and p2w together, there are a lot of lootbox type of items and lotterys.
- They added macro loop and next target loop system, so looks like 80% of the population is farming AFK, some of them (many) probably bots, easy to tell even from their movement when you look.
- Adena and drop rate is low, but if you have time and you can play the market you can tolerate that.
If you wish to chill and farm or find a clan or CP you will be fine. If you want to be competative with the top 5% and be a hero from your own strength without cash --> “Run you fools!”
GL!
