Is 4k low? Yes. Do this make the player garbage "tier"? First "tier" does not exist in this game, players or the community makes it up. 4k dps means nothing until you link it with something in game:
1. will I take him for a sub position of my statics? No.
2. would I like to meet and play with him again in PF content like dog farm? No. So I blist him later
3. will I blame and shame him for the low dps during the instance? No. I'd get banned for that.
4. will I quit that instance because this low dps? Depends, for PF raid content, sure. For random DF fight of tomes or exp. lol why borther, just blist him later.
So it all ups to you or each individual player, "tier" doesn't exist. It's not even worth to bring it up to be honest.
