Firstly, notice that I said I don't know whether melee burn in sea is as good as in other places.
Secondly, did you actually look at his screenshot? He got chain 5. So what? How exactly that disprove that manaburning is better in sea than in other areas while melee burning is not? He didn't even say manaburning sucked, just that is was boring, a sentiment echoed by others. That's a non-argument anyway because you can say the same thing about melee burn parties if you were so inclined.
The whole complaint that you have is melees can make 13k/hr or whatever while you're relegated to a horrible 8k/hr max with manaburn, which Lockecole is saying is bullshit.
