You all realize that there is NO right or wrong answer to "should HGWT remain", right?
It's a question of perception, game experience, and habit mostly.

Everyone will have a different place where they draw the line of "what is too much", teleports, summoning stones, HGWT, insta-port to boss etc.. nobody is right or wrong, and every one has their opinion.
That obvously includes Blizzard, and THEY are the ones to draw the line for us all. Someone has to do it after all.
