There are no "I gotta have that skill" in POE.

I remember long ago playing Diablo 2 see'ing another player whirlwind through mobs while leeching life and I though to myself; "I gotta have that". So I made a new barbarian character. While playing a barb I saw a necro with an army of skeletons and thought to myself, "I gotta have that". So I made a new necro character. While playing my necro character I saw an amazon shootin those lightning javelins and though to myself, "I gotta have that" so I created a new amazon character.

In POE1 and POE2 there are no "I gotta have that" skills.

1) The good skills clear the screen so fast I can't even see what is doing the killing. Half the time I can't even keep up with the player doing the killing, sometimes when I load into the map the player is already halfway across the other end of the map and I can't even catch up to leech XP off of em.

2) The visual spam prevents me from see'ing what other players are doing half the time. Eventually my brain just shuts down cause it can't handle the visual disco acid trip, and by the time I'm done following the guy around leeching XP for a couple maps I don't want to see that skill ever again cause my eyes are bleeding and my brain is tired.

There are plenty of skills both in POE1/POE2 that I've said..."I need that."
