EQ2 encounters and combat felt like a spreadsheet formula. Totally predictable whether you would win the fight based completely on the mobs level compared to yours.
No tactics or strategies like EQ, you know with 98% certainty if you win or lose before you even engage. So many of the abilities where DMG + Minor Stat Reduction, and whatever the secondary component was of the ability felt completely worthless and pointless. It never felt like you were balancing your resource pools, you just face smash your keyboard till shit was dead.
The social agro, small group-pulls, and leashing were all fucking stupid as well. It all felt so artificial. EQ felt alive, dangerous, and unpredictable. EQ2 felt like a video game.
Their fundamental gameplay loops were fucked out of the gates, in the attempt to be casual and solo-friendly. The only people that don't know that or acknowledge it never played a real MMO like EQ1.
