Are the tactics easier now?
Sometimes puzzles are easier because you know the key pattern. If you saw a much lower rated puzzle that uses an unfamiliar idea, it can be much harder to solve.
Sometimes you can also use logic, like if the opponent is threatening mate in 1 and you can't defend it, then you know all the moves in the solution are checks.
Sometimes people are biased. They pay attention to their best wins (or solved puzzles) while ignoring their worst losses (or failed puzzles).
For example, if you solve 2000 puzzles easily, and consistently, then your tactics rating would be above 2000, but right now it isn't, so...
