if you want to be big ignore muscular endurance. nothing is wrong with getting a pump, it is usually inevitable from any type of hard work. it is not, however, an indicator of anything except blood swollen tissue
I don't mind having muscular endurance while building muscle. I do push myself rather hard and usually hit the last 1-2 sets of each exercise I do to failure. I do aprox 3-4 exercises per muscle. I just don't see how I could work out less and get the same gratification I am getting now. I am sure if I tried lifting even harder and less frequently maybe I would put on size quicker but I'm not big into the cutting/bulking thing plus I am not in a hurry to get big. I just love working out and getting big is a side effect for me. I know many of you think I work out too much so what (constructive) advice could you give to somone that NEEDS to do something intense on a daily basis? I mean even on my off day I usually swim or run for 30-60 minutes at the least.....
and as far as what PUMP is thanks for defining it but I was already aware of what it was. Doesn't make me enjoy it any less, so I'll say it again I love the PUMP I get from working out, no matter how temp it is.
