Ok, I don't know all the exact details of how it works out. But from my experience (pun intended) The difference in experience works out fairly well ...
I have a lvl 47 tank who only has 3086 base HP unbuffed and I do fine pulling mobs. I have tanked kappa elite's fine with a healer and not wearing a shield...It is like he said. It all depends on your stats. Now dueling on the other hand....I wont go their. I get my butt stomped lol.
why would u need say 6k hp at 45 when u could have 4k and have more stats like str and dex to make it go faster or agility to make ti so they hit u for less. i dont use me 4.5k i use max 1200 of it thats when i pull like 3 on a spawn. (rarly im prettty good at pulling now) im not wearing anything bo
